     BACKGROUND  
       [0002]     The Internet is increasingly being used to conduct “electronic commerce,” in part, because it facilitates electronic communications between vendors and purchasers. For example, the Internet may be used to unite sellers of goods or services, such as with purchasers wishing to buy such goods or services. For example, some web sites allow users to enter specific data with respect to items they wish to purchase or sell. After uniting a buyer with one or more merchants, the parties may then complete a business transaction. Often, these web sites, acting as intermediaries or “infomediaries,” facilitate commercial transactions more automatically and in a more targeted fashion than prior systems such as advertising, cold-calling, etc.  
         [0003]     There are many existing web sites that act as intermediaries between buyers and sellers (e.g., sites related to buying and selling automobiles, real estate, electronics, pets, etc.). Thus, finding ways to attract users to a particular site is often an important consideration. In addition, once users are convinced to use a particular site, providing useful information, especially with respect to the products or services being promoted on the site, may be helpful in retaining users and encouraging commerce.

     DETAILED DESCRIPTION  
       [0019]     The invention will now be described with respect to various embodiments. The following description provides specific details for a thorough understanding of, and enabling description for, these embodiments of the invention. However, one skilled in the art will understand that the invention may be practiced without these details. In other instances, well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments of the invention.  
         [0020]     It is intended that the terminology used in the description presented be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain specific embodiments of the invention. Certain terms may even be emphasized below; however, any terminology intended to be interpreted in any restricted manner will be overtly and specifically defined as such in this Detailed Description section.  
         [0000]     I. Overview  
         [0021]     A computerized aerial mapping system or facility with possible enhancements provides various map-based features using aerial map information along with other information. In some embodiments, the aerial mapping facility presents a nationwide aerial map to a user using, for example, aerial photographs or satellite imagery and allows a user to “zoom in” on an area or even on a specific property of interest (e.g., a house on Seattle&#39;s Lake Wash.).  
         [0022]     The aerial mapping facility may incorporate an overlay of multiple listing service (MLS) data that allows the aerial mapping facility to provide special indications of houses and/or properties that are for sale (e.g., properties for sale may be highlighted on the map using a colored outline around the property). In addition to MLS data overlays, many different types of data overlays may be applied to the aerial map information and this data may be obtained from a variety of data sources. Examples of such information may include county tax parcel location data, tax assessor data, data regarding points of interest, local weather data, average house price, cost-of-living estimates, yellow pages data, etc. In general, the overlay information may include any type of location-based data. The aerial mapping facility may also integrate various type of geographic vector and point data (e.g., shown as drawn-in information in the aerial map) so that streets, boundaries, and other information that are not evident from the aerial picture alone may be identified.  
         [0023]     In some embodiments, users may access the aerial mapping facility from a web site. The web site server may employ a viewer that allows a user to zoom in on a map via a web browser without needing to download a specific client application. Any range of zooming may be implemented. For example, at the highest level, the map may cover an entire country or continent, or even the whole world. It may also be possible to include maps from the aerial mapping facility in emails or other types of user notifications. For example, a user may sign up for a “Just Listed” service that enables him or her to receive emails (containing aerial map features, photos, etc.) each time a home or property goes up for sale in an area of interest that the user has identified. In some cases, the user may be able to set filters to include/exclude certain new listings (e.g., listings outside of the user&#39;s price range and/or size requirements). In a similar example, an email update may be sent to a user that includes recent home sales within the user&#39;s area, and may include a picture or map. Information regarding open houses in the area may also be provided in this way (with or without a map). In some cases, it may be possible for a user to designate an area of interest by “lassoing” an irregularly shaped area using a graphical interface tool provided by the aerial mapping facility.  
         [0024]     A provider of the aerial mapping facility may generate revenue in multiple ways. In some embodiments, it may be possible to license to various real estate professionals access to aspects of the aerial mapping facility. For example, by performing certain actions from a primary web site provided by the aerial mapping facility, the facility may take the user to a real estate professional&#39;s personal home page. In addition, this real estate professional may have registered and paid a fee to receive bundles of leads generated by users zooming in within a designated geographical area. In this way, the aerial mapping facility may be used to collect information from consumers (e.g., home buyers and home sellers) in order to generate leads (e.g., bundles of leads) for real estate professionals or, more generally, providers of goods or services. To enable the collection of leads, users may be taken to a registration page after zooming in on certain features of the map.  
         [0025]     A provider of the aerial mapping facility may also generate revenue by allowing click-through access to an advertiser&#39;s own web page via the maps. For example, a user that clicks on a home identified as being for sale on the map may be taken to the selling agent&#39;s home page. Likewise, clicking on an indication of a restaurant on the map may take the user directly to the web page for the restaurant. In a similar example, an advertiser may pay a fee for each time its icon is displayed on the map as a point of interest (e.g., advertiser pays two cents each time its fast food icon is displayed on a map as a point of interest).  
         [0026]     In yet another example, revenue may be generated by having real estate professionals license the mapping technology so that they can provide it from their own personal web pages (independent of whether the real estate professional has registered to receive leads generated using the primary mapping web site). For example, in such cases, the provider of the aerial mapping facility may host the real estate professional&#39;s web site and thereby provide the mapping technology.  
         [0027]     In some embodiments, the user may be introduced to the aerial mapping facility via a video demo that starts automatically when the user first arrives at a home page associated with the aerial mapping facility. Some of the options provided to users from the home page may include viewing an aerial image of the user&#39;s own home (e.g., by entering address information into text fields), searching homes for sale (e.g., by zooming in on desired areas using the interactive map), seeing the prices of recently sold homes, etc. Registration opportunities may exist at various times during a user&#39;s interactive session. For example, if the user selects to search for homes for sale, a screen asking the user if he or she wants to register may first pop up.  
         [0028]     In some embodiments, the aerial maps provided by the aerial mapping facility may include color-coded aspects. For example, an age map may show the age of homes using yellow (for newly built homes) fading to red (for older homes), thus using color to show a concentration of new versus older homes in a selected area. In addition to color, other indicators may be used to identify items of interest (e.g., special icons, flashing identifiers, audio identifiers, etc.) For example, flashing may be used to indicate items of interest, such as an open house.  
         [0029]     The mapping technology may be available from a user&#39;s personal computer, as well as from other user devices including portable devices (e.g., mobile phones and computers in automobiles).  
         [0000]     II. Representative Environment and Sample Data Scheme  
         [0030]      FIG. 1  and the following discussion provide a brief, general description of a suitable computing environment in which the invention can be implemented. Although not required, embodiments of the invention will be described in the general context of computer-executable instructions, such as routines executed by a general-purpose computer, such as a personal computer. Those skilled in the relevant art will appreciate that the invention can be practiced with other computer system configurations, including Internet appliances, hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, network PCs, mini computers, mainframe computers, and the like. The invention can be embodied in a special purpose computer or data processor that is specifically programmed, configured, or constructed to perform one or more of the computer-executable instructions explained in detail below. The invention can also be practiced in distributed computing environments where tasks or modules are performed by remote processing devices, which are linked through a communication network. In a distributed computing environment, program modules or sub-routines may be located in both local and remote memory storage devices.  
         [0031]     Unless described otherwise, the construction and operation of the various blocks shown in  FIG. 1  are of conventional design. As a result, such blocks need not be described in further detail herein, as they will be readily understood by those skilled in the relevant art.  
         [0032]     Referring to  FIG. 1 , an enhanced aerial imagery system  100  may include one or more client computers  102 , each of which includes a browser program module  104  that permits the client computer  102  to access and exchange data with the Internet, including web sites within the World Wide Web portion  106  of the Internet (or via another network such as a WAN or LAN, cellular phone network, etc.). The client computers  102  may include one or more central processing units or other logic processing circuitry, memory, input devices (e.g., keyboards and pointing devices), output devices (e.g., display devices and printers), and storage devices (e.g., fixed, floppy, and optical disk drives), all well known but not shown in  FIG. 1 . The client computers  102  may also include other program modules, such as an operating system, one or more application programs (e.g., word processing or spreadsheet applications), and the like.  
         [0033]     An intermediary system or facility  108 , coupled to the World Wide Web, or “Web”  106 , performs much or all of the aerial mapping and lead generation processes. At least one enhanced imagery database  110 , coupled to the intermediary facility  108 , stores data exchanged between the client computers  102  and one or more agent computers  112  under the enhanced aerial imagery system  100 , as described below. Other sources for data used by the enhanced aerial imagery system  110  may also exist, including third-party sources. Each agent computer  112  is similar to the client computers  102 , and includes a browser  114  to permit the agent computer  112  to access and exchange information with the Web  106 .  
         [0034]     In some embodiments, the intermediary facility  108  may include a map view data server  116  for handling the serving of enhanced aerial images and/or a lead generation server  118  for handling lead generation for real estate professionals or other providers of goods or services. In some embodiments, the map view data server  116  handles various functionality, including allowing a user to zoom in and out on an enhanced aerial map without needing to download a specific client. The scope of the high level maps may range from a single property to the whole world. The map view data server may also provide miscellaneous tools, such as a graphical tool that allows a user to select an area of interest by drawing an irregularly shaped area on the map. A rapid access file storage system  132  may function to store image data and associated data when in use by the map view data server  116 .  
         [0035]     The lead generation server  118  may implement its own functionality related to lead generation (e.g., for real estate professionals). For example, the lead generation server  118  may employ an exclusive marker area (EMA) scheme where real estate professionals are exclusively (or semi-exclusively) assigned to areas (e.g., based on zip codes, census block data, or other factors), and then notified of users showing interest in homes in such areas. Information used by the lead generation server  118  may be stored in the user database  120 . In a second example, the lead generation server  118  may access an external multiple listing service (MLS) to generate leads based on user requests that have been obtained through the MLS. These leads may then be bundled and sold in packages to subscribing parties. A combination of the two approaches described above may also be employed, where the lead generation server  118  generates leads through an EMA or similar scheme that are distributed and sold as bundles.  
         [0036]     The intermediary facility  108  may also include a web page manager component  122 , a database manager component  124 , an analysis process component  126 , a notification process component  128 , and a management process component  130 , as well as other components not shown in  FIG. 1 . As described more fully below, the notification process component  128  may facilitate electronic messaging, such as via email, among the client computers  102 , intermediary facility  108 , and agent computers  112 . Alternatively, or additionally, the notification process  128  may provide notification to agents or clients (e.g., real estate professionals and homeowners, respectively) via telecommunications devices. In this way, the notification process may provide updates or other information to users, particularly potential buyers. For example, an email update could include recent sales information for an area, data regarding open houses in the area (with or without a map), open house data, etc. The intermediary system may allow users to specify areas for which they wish to receive such updates.  
         [0037]     Referring to  FIG. 2 , the at least one enhanced imagery database  110  of  FIG. 1  is shown in more detail. In some embodiments, the map view data server  116  may handle many different data sources, although in its simplest form, it may handle only an underlying map layer made up of satellite imagery  202 , aerial photo imagery  204 , and/or the like. These imagery data sources may sometimes be referred to as “Digital Orthorectified Quadrangles” (DOQs). Digital orthography is the process by which images are adjusted to account for elevation changes so that aspects of the image can line up appropriately. For example, the United States Geological Survey (USGS) has been making high-resolution imagery of this type available on a city-by-city basis. Likewise, many private companies provide such imagery.  
         [0038]     In some embodiments, aerial imagery ( 202  and  204 ) is imported into the intermediary system  108  using one or more tools. For example, one or more tools may break down large image files into many smaller files (e.g., “map tiles”) and generate an index file to help locate the many smaller map tiles. The map tiles may go through some additional post-processing prior to use, such as coloring the water or re-coloring the map, or adding additional layers to the tiles. In some embodiments, map tiles need to be image files. Rather they can be any information/data that facilitates the electronic display of one or more maps. A single map displayed on a screen may be comprised of one or many map tiles.  
         [0039]     In some embodiments, map tiles are flattened, two-dimensional images of a round (i.e. three-dimensional) Earth. The mathematical function for transforming a 3-D surface to a 2-D one is sometimes called a “projection”. Aerial images are stored in projections that cover relatively small areas localized to a given city, region, or state. This allows the flattened map tiles to represent the 3-D earth as accurately as possible. Additional point and vector layers (e.g. data overlays) may be added to the map. These layers can be stored in the same mathematical projection as the map itself, but more likely will be stored in either the original 3-D coordinate system (latitude/longitude) or a completely different mathematical projection entirely. In order to accurately overlay these points and vectors on the aerial images, all points are transformed in real-time from their original coordinate space to the map tile projection coordinate space.  
         [0040]     In some embodiments, the one or more tools may generate such map tiles at many resolutions to enable effective zooming in/out. For example, each time a user zooms in on a map, a new set of map tiles (e.g., a three-by-three square of nine map tiles configured at a higher resolution and covering less geography) may replace an earlier set of map tiles (e.g., a three-by-three square of nine map tiles configured at a lower resolution and covering a greater geographical area). To enable quick exchange of map tiles, the one or more tools may request Information about relevant map tiles and the cache such information for later use. For example, while displaying information at one resolution, the one or more tools may anticipate that the user is going to want to zoom in and accordingly, request and cache a next higher resolution of map tiles. Likewise, the one or more tools may request adjacent map tiles and store and cache them in anticipation of a user performing “panning” on a currently displayed map. In this way, the user can experience near seamless panning, zooming, etc., despite the fact that images may themselves comprise large amounts of data.  
         [0041]     Any number of overlays may be added on top of the map layer, with each overlay including additional data of interest. Sometimes, such overlays are purchased from vendors while others are downloaded free from government agencies. In some embodiments, the overlays may comprise information based on vectors, points, or both vectors and points. For example, U.S. city names information  206  may aggregated into a overlay that defines cities using points, which are then drawn as groups of pixels (or icons) on top of the aerial imagery to identify cities and associated information (e.g., state capitals, etc.). In another example, points of interest information  228  or select amenities information  236  may provide similar overlays using points (e.g., identifying restaurants, airports, libraries, museums, amusement parks, shopping centers, grocery stores, etc.). In some cases, the user using filters or searching techniques may access these points of interest.  
         [0042]     Likewise, some overlays may be based on vector information and may provide displays of lines (as in the case of roads) and polygons (parcel outlines, park boundaries, state boundaries, etc.) on top of a map layer. For example, neighborhoods information  208 , boundaries information  210 , roads information  212 , tax information  214 , commercial use information  216 , bodies of water information  218 , parks information  220 , schools information  222 , etc., may all be defined and illustrated using vectors. Additional vector layers may be added when available. For example, a county parcel map (also called a “Base Map”) may be distributed by some county agencies and, when accurate, may be an appropriate overlay on aerial imagery. Like the points described above, these vector-based overlays may also be accessed by searching techniques (e.g., using keywords) or by filtering techniques, etc.  
         [0043]     While specific types of layering/overlay schemes based on specific types of information are described above, almost any type of data that has any geographic relevance can also be tied to the maps of the aerial mapping facility. Such data may include county tax assessor records  214 , real estate information related to current listings  224 , topography information  226 , real estate information related to past listings (previously sold)  230 , information related to the age of various buildings or structures  232 , real estate information related to open houses  234 , information related to garage sales  238 , census bureau and state traffic analysis (not shown), neighborhood and community statistics (not shown), geologic data, zoning data, construction or other permit data, etc. In some embodiments, the information used for overlays may be associated with more detailed information that may be presented when a user clicks on an object identified on a map. Likewise, it may be possible for the user to click to add or remove different layers of data. Each layer may be represented by a different color or other attribute (vector characteristic, etc.).  
         [0044]     With respect to implementation of such overlays, in some embodiments, point and vector overlays can be delivered as database tables or flat files (e.g., ESRI shapefiles). Shapefile is the most common flat file format supported by nearly all Geographic Information System (GIS) data suppliers. In some embodiments, shapefiles are run through a tool associated with the intermediary facility  108  and imported into the database to allow faster lookup of the data when performing rendering. To help with the matching up of map images to overlay information, the overlay information, which may be implemented using points and/or vectors, may be structured using a geographical coordinate system similar to the geographical coordinate system used in GIS maps. In this way, mathematical projections can be used to match overlays with maps, so that the overlay information lines up with the map information as accurately as possible. For example, in some embodiments, point coordinates may be stored in a particular mathematical projection inside a file containing map or overlay information. Various aerial imagery coordinates may also be stored using mathematical projections, but such projections may not be the same as the projection for each point/vector layer. Because each point/vector layer consists of individual points and or vectors, those points/vectors can be “re-projected” to line up on the aerial imagery.  
         [0045]     Alternatively, in addition to the data scheme described above, the aerial image maps can be integrated with data from other data sources, such as third party data sources. Accordingly, there are few limits on what types of information can be shown on such maps. Some examples include source specific information about points of interest, weather information, sports information, news information, current cost of living information, store hours information, and so forth.  
         [0046]     Referring to  FIG. 3 , the various users of the system may be assigned records in a user database  120  to facilitate lead generation or similar functionality. For example, each real estate professional (or other seller or provider of goods or services) may be assigned a user database record  340 . Each record may include an agent ID field  342 , an agent name field  344 , an assigned zip code(s) field  346 , an email address field  348 , a phone number field  349 , a company or employer field  350 , an address field  352 , a payment field  354 , a contacts field  356 , a contacts status field  358 , and a contacts calendar field  360 . Of course, each record can include some or all of these fields, or additional fields not shown in  FIG. 3 . In one embodiment, only one real estate professional is assigned to each zip code, although in alternative embodiments, more than one agent can be assigned to a single zip code.  
         [0047]     In addition to records for agents/professionals, the user database may also include records for future purchasers of goods or consumers of a service (e.g., home buyers or sellers). For example, each record may include a user ID field  362 , a user name field  364 , an email address field  366 , a phone number field  368 , an address field  370 , and one or more fields providing information on an item or service associated with the user  372  (e.g., identifying information about a home the user wishes to purchase or sell).  
         [0000]     III. Sample User Interfaces  
         [0048]      FIGS. 4A-4G ,  5 A- 5 C,  6 - 7 ,  8 , and  9 A- 9 E are display diagrams showing examples of various user interface features, screens, and/or web pages associated with embodiments of the aerial mapping facility. The screens or web pages of the Figures may be implemented in C++, Java, or JavaScript, or as web pages under XML (Extensible Markup Language), HTML (Hypertext Markup Language), Flash! ASP.net, or any other scripts or methods of creating displayable data, such as the Wireless Access Protocol (“WAP”). The screens or web pages provide facilities to receive input data, such as a form with fields to be filled in, pull-down menus or entries allowing one or more of several options to be selected, buttons, sliders, hypertext links or other known user interface tools for receiving user input. While certain ways of displaying information to users is shown and described with respect to certain Figures, those skilled in the relevant art will recognize that various other alternatives may be employed. The terms “screen,” “web page” and “page” are generally used interchangeably herein.  
         [0049]     When implemented as web pages, the screens are stored as display descriptions, graphical user interfaces, or other methods of depicting information on a computer screen (e.g., commands, links, fonts, colors, layout, sizes and relative positions, and the like). In general, a “link” refers to any resource locator identifying a resource on a network, such as a display description provided by an organization having a site or node on the network. A “display description,” as generally used herein, refers to any method of automatically displaying information on a computer screen in any of the above-noted formats, as well as other formats, such as email or character/code-based formats, algorithm-based formats (e.g., vector generated), or matrix or bit-mapped formats. While aspects of the invention are described herein using a networked environment, some or all features may be implemented within a single computer environment.  
         [0050]      FIG. 4A  is an example of a screenshot of a home page  400 . The home page  400  of  FIG. 4A  may represent a portal by which a user enters the aerial mapping facility. For example, it may be utilized to facilitate real estate sales, generate leads for real estate professionals, facilitate entry to agent web sites, and so forth. In addition, the portal can be tailored to provide different aspects to consumers than the aspects provided to real estate professionals. The home page  400  shows a high-level aerial image of an interactive map  402  covering the United States and parts of North America. The user may be provided with various options for interacting with the map  402 , including zooming in on aspects of the map using zoom features  404 , which may include a click-sensitive map that the user can click on to drill down. For example, a user may be able to click anywhere on the U.S. map to zoom down to an individual home, as shown in a screenshot  420  of  FIG. 4B . It may also be possible to reset the map using the zoom features  404  or other features (e.g., shortcut keys).  
         [0051]     Additional user interface features may include a SEE AN AERIAL VIEW OF MY HOME feature  406 , a SEARCH HOMES FOR SALE feature  408 , and a SEE RECENT HOME SALES ON MY STREET feature  410 . To provide this information, the map  402  may include an overlay of multiple listing service (MLS) data to display indications of houses that are for sale in an area displayed on the map. Because of the high-level nature of the map  402 , as can be expected, the overlay of MLS data is not shown in  FIG. 4A , but is shown in subsequent Figures (e.g.,  FIG. 4D ). In this way, the enhanced aerial imagery may generate leads for sales, such as home sales.  
         [0052]     A layering tool bar  412  depicted here at the bottom of the map  402  allows a user to select various informational layers that can be applied to the map. Other options for allowing users to select layers may include expandable menus or other UI features. For example, applying a STREETS layer using the layering tool bar  412  will allow users to view street location, names, and numbers when the map is zoomed in to an appropriate level of detail. Similarly, applying a SCHOOLS &amp; PARKS layer using the layer tool bar  412  will display identifiers associated with schools and parks when the map is zoomed in to the appropriate level of detail. An AGENTS layer, if selected, will allow the user to see an indication of any real estate professionals assigned to a particular region. For example, real estate professionals may sign up with and pay a fee to the provider of the aerial mapping facility to be associated with a specific area of the map. A POINTS OF INTEREST layer may also be provided (to display points of interest, e.g., restaurants, shopping centers, airports, etc.) within a given area. Accordingly, the enhanced aerial imagery scheme can be used to generate revenue by promoting particular points of interest (e.g., a two-cent royalty may be collected each time an icon identifying a McDonald&#39;s restaurant is displayed on the map). A FACTS layer may allow a user to view more detailed facts (when available) about a particular point or vector on the map. It is not difficult to see that the information associated with the layers described above may be useful to future home buyers, sellers, and real estate professionals, as well as other users.  
         [0053]     Referring to  FIG. 4C , a screenshot  430  shows a result of the user selecting or clicking on the SEE AN AERIAL VIEW OF MY HOME feature  406 . As shown, an ADDRESS text box  432  and a ZIP CODE text box  434  are displayed, into which the user enters his or her address “8301 Overlake Drive” and zip code “98039,” respectively. The user may then submit the information by selecting a GO button  436 . As a result of selecting the GO button  436 , the user is taken to a page that shows the user&#39;s home identified in an enhanced aerial map. An example of such a page is shown in  FIG. 4D .  
         [0054]      FIG. 4D  shows a screenshot  440  of a map  442  after the user has selected to zoom in on his or her own home at “8301 Overlake Drive.” An indication of the user&#39;s home  444  is highlighted using a yellow outline (e.g., vector layer). The user may be instructed to click on the identified area to zoom in. In addition to the user&#39;s own home, various properties are highlighted using a different color outline, and may indicate homes for sale  446  in the area surrounding the user&#39;s own home. This information may be provided based, for example, on an overlay of MLS data, or on other information. The user is also instructed to “Click any property to see more.” In addition, various parks  448  are identified on the map, as the SCHOOLS &amp; PARKS layer is selected in the layering tool bar.  
         [0055]      FIG. 4E  shows an example of a screenshot  450  of a registration view  452  from which a user may provide registration information. This information may later be used to generate leads for real estate professionals, or for sending notifications to the user. In some embodiments, the registration view  452  may be displayed after the user performs some activity associated with an enhanced aerial map, such as selecting to invoke a SEARCH HOMES FOR SALE feature  408 , as shown in  FIG. 4A , or clicking on a property on a map that is highlighted as being for sale (e.g., home  446  in  FIG. 4D ). In some embodiments, the registration is optional, or alternatively required if the user would like to receive further information. The registration view  452  may include an explanation  454  of reasons why a user should register. It may also include a login area  456  for users that have previously registered as well as input fields  458  allowing new users to register. One or more checkboxes may be provided that allow users to elect certain services or features associated with the aerial mapping facility. For example, users may be able to select SHOW ME CURRENT MLS LISTINGS  460 , SHOW ME RECENT SALES IN MY AREA  462 , and/or SEND ME PINPOINT UPDATES  464 . When a user completes registration or login, the user may then select a GO button  466  to submit the information.  
         [0056]      FIG. 4F  is a screenshot  470  showing an agent-specific screen  472  that may be displayed to the user after he or she selects the GO button from the registration view  452  of  FIG. 4E . The agent-specific screen  472  may include an agent banner  474  that identifies the real estate professional(s). The agent-specific screen  472  may also display a property summary  476  that provides detailed information for the initial property that the user selected to be brought to the agent-specific screen  472 . In some embodiments the user may select from various tabs  478  and/or subtabs  480  provided on the agent-specific screen  472 . Examples of such tabs  478  include a HOME tab, a SEARCH FOR PROPERTIES tab, a VIEW RECENT HOME SALES tab, a RESOURCES tab, an ABOUT US tab, etc. Many of these tabs are self-explanatory. In the illustrated example, a SEARCH FOR PROPERTIES tab is selected, and results in the display of various subtabs  480  including a BASIC SEARCH subtab, an ADVANCED SEARCH subtab, a PROPERTY RESULTS subtab (currently selected), a PROPERTY DETAILS subtab, a MY FAVORITES subtab, a MY SAVED SEARCHES subtab, etc. As with the tabs  478 , the subtabs  480  shown in the illustrated example are self-explanatory. The property results subtab is shown in more detail, and provides various listings  482  within a given area, as well as an interactive map  484  and related features.  
         [0057]      FIG. 4G  is a screenshot  490  showing a property details screen or view  492  associated with a property details subtab on the agent-specific screen  472  (also displayed in  FIG. 4F ). In the illustrated example the property details view  492  shows a property summary  494  and provides access to various images of the selected property via thumbnails  496  and a general image  498 . Other examples of information that can be shown in the property details view  492  include a virtual tour (e.g., panning images showing different views of a room in a house), video, etc.  
         [0058]     While not shown in the Figures, other interactive map options may be provided. For example, some enhanced aerial maps may provide access to “coupons” associated with businesses. Such coupons may be presented (e.g., via a web site or pop-up) when a user clicks an indication of specially marked businesses (e.g., highlighted in yellow or some other color on the aerial map). Revenue can be generated accordingly (e.g., for just posting the coupon, for each impression, for each click-through, for a percentage of each sale, etc.).  
         [0059]      FIGS. 5A-5C  and  6 - 8  are display diagrams showing examples of data overlay schemes (e.g., layers) that may be applied by the aerial mapping facility. This data can include any type of location-based data, such as real estate data, points of interest (commercial establishments), and so forth. For example,  FIG. 5A  shows a home age overlay “heat map” where the aerial map is displayed showing various colors assigned based on the age of homes. For example, dark red may indicate older homes (early 1900s), orange may indicate homes from the 1950s and 1960s, and yellow may indicate newer construction. Other interesting categories could also be mapped (e.g., appreciation, taxes, sales price, etc.). In this way it is easy for users to locate concentrations of homes based on age, appreciation, etc. Likewise,  FIG. 5B  shows an overlay of parks and water, while  FIG. 5C  shows an overlay of homes for sale, parks, schools, and water, all in combination. By providing features such as these, the aerial mapping facility may allow future homeowners to become more familiar with important factors within the areas in which they are looking to buy. In turn, this will attract more users (and return users) to the web site, and thereby generate more leads, advertising opportunities, etc.  
         [0060]      FIGS. 6-8  show various examples of one embodiment of the aerial mapping facility where users can access various overlays and associated features through the use of tabs on a user interface. Referring to  FIG. 6 , examples of such tabs include a VIEW tab  602 , a SEARCH tab  604 , a DETAILS tab  606 , a HISTORY/TAXES tab  608 , and an ADVANCED tab  610 . As shown in  FIG. 6 , the VIEW tab  602  may include an OVERLAYS section  612 , which allows users to select various overlays (e.g., parks, schools, neighborhoods, etc.) to apply to an interactive aerial map  614 . Each selected overlay may then be associated with a particular color on the map. The OVERLAYS section  612  may also provide access to a customizable overlay via a search field  616 , where the user may enter in keywords to identify points of interest (e.g., grocery stores) so that locations associated with such search results may be displayed on the interactive aerial map  614 . A FOR SALE section  618  may provide input fields so that a user can filter out homes for sale in the area that meet specified requirements (e.g., price range, residential versus condominium, number of bedrooms, etc.). Likewise, a COMPS  620  section may allow a user to input information so that the user can see what other comparable homes have sold for in the recent past.  
         [0061]      FIG. 7  shows an example of information provided under the DETAILS tab  606 . For example, the DETAILS tab  606  may provide a photograph  702  of a selected home (identified using a unique color outline on a map  704 ), as well as a detailed description  706  of the home. Using a forward/backward feature  708 , it may be possible to scroll to detailed information about another home displayed on the map.  
         [0062]      FIG. 8  shows an example of information provided under the HISTORY/TAXES tab  608 . For example,  FIG. 8  shows basic tax information  802  for a selected residence, as well as a map  804  with tax plats shown in red outlines. In addition to basic tax information, the aerial mapping facility may provide tax information for recent sales of the selected home  806 , as well as a feature  808  that allows users to find comparable properties in the area (e.g., comparable with respect to tax information).  
         [0063]      FIGS. 9A-9E  provide examples of data charts/reports used in conjunction with the enhanced aerial maps. For example, these reports may provide statistical information as well as data comparisons among selected neighborhoods, areas, groups of homes, etc.  FIG. 9A  is an example of a report that provides information on average appreciation of homes in a given set of areas versus the year built.  FIG. 9B  is an example of a report that identifies the percentage by which the median sales price has changed for Seattle neighborhoods over a 20-year period.  FIG. 9C  is an example of a report that shows how waterfront home values in a given area fluctuate more greatly than non-waterfront homes in the same area.  FIG. 9D  is an example of a report that shows a change of median sale price for selected neighborhoods over time.  FIG. 9E  is an example of a report that shows trends in King County home sales volume over 20 years.  
         [0000]     IV. Lead Generation Examples  
         [0064]      FIG. 10  is a flow diagram of a representative implementation of a lead generation routine  1000 , possibly used in combination with the enhanced aerial imaging techniques described above. Beginning at block  1002 , the routine  1000  (e.g., via the lead generation server  118  of  FIG. 1 ) identifies real estate professionals and assigns them to particular zip codes or other designations in the appropriate database (e.g., the user database  120  of  FIGS. 1 and 3 ). For example, each real estate professional may be assigned a database record, as described in more detail with respect to  FIG. 3 . At block  1004 , the routine  1000  presents lead generation opportunities to homeowners, potential home buyers, or other members of the public. An example of such lead generation opportunities includes the aerial maps described above. Additional lead generation opportunities may result from posting banner advertisements on selected web pages or sending targeted email messages or other direct advertisements to the client computers  102 . The costs for the advertisements may be billed based on the number of homeowner visits to the web site, or the number of homeowners who visit the web site and actually complete a web page form, or by other methods, including methods described above relating to aerial maps.  
         [0065]     At block  1006 , the routine  1000  receives a home valuation request form or home inquiry request form from a homeowner. For example, in the illustrated embodiment of  FIG. 1 , the client computer  102 , via the browser  104 , may retrieve a display description, e.g., a web page information request form from the web page manager component  122  of the intermediary facility  108 . An example of such a request form is shown with respect to  FIG. 11  (and also with respect to  FIG. 4E ), and may be displayed after a user selects a home using an enhanced aerial imagery map. A request form  1100  includes fields to be filled in by the homeowner (or future home buyer), some of which include drop-down entries or buttons to permit the user to select one of several options. As shown, the request form  1100  may include contact information  1102  for the homeowner (or future home buyer) (e.g., property&#39;s address; property&#39;s zip code; neighborhood name; homeowner&#39;s/buyer&#39;s name; homeowner&#39;s/buyer&#39;s address, including city, state, and zip code; home phone; work phone; email address, etc.) and property information  1104  (e.g., type of property; style of home; approximate year built; number of bedrooms; number of full bathrooms; number of half bathrooms; number of fireplaces; square footage; parking spaces; list of recent improvements; primary/rental home; rating of overall condition; when the homeowner plans to sell; where the homeowner is moving; whether the home is currently listed with an agent; how the homeowner heard about the existence of the web site listing this form; whether the homeowner would like to receive a newsletter, etc.). After the homeowner/future home buyer has filled out the fields in the request form  1100 , the homeowner selects a submit query button  1106  to send the completed form from the client computer  102  to the intermediary facility  108 , via the Web  106 .  
         [0066]     While not shown, the request form  1100  may also include other features such as a mortgage calculator, a moving calculator, an insurance professor, a library, a relocation wizard, etc. For example, the mortgage calculator determines home buying power from the point of view of a lender by analyzing a broad spectrum of financial and mortgage scenarios. The moving calculator estimates high and low estimates of moving costs for local and long-distance relocations. The insurance professor compares insurance rates in a number of cities for a variety of insurance carriers. The library includes various articles or other data relevant to a homeowner who is interested in selling a home. The relocation wizard provides a personalized and detailed relocation time line that helps homeowners get and stay organized before and during a move. Other features (not shown) may include a home seller tips section, which provides tips on helping a homeowner sell a home. These and other features are known to those skilled in the relevant art and need not be described in further detail herein.  
         [0067]     At block  1006 , the routine  1000  adds the data in the received request form  1100  to the appropriate database (e.g., the user database  120  of  FIGS. 1 and 3 ). At block  1008 , the routine  1000  identifies a selected agent in the appropriate database. For example, with respect to the components of  FIG. 1 , the database manager component  124 , together with the lead generation server  118 , queries the user database  120  for the record having an assigned zip code field with a zip code that matches a zip code field in the received request form  1100 . Other mappings (besides zip code mappings) may be possible.  
         [0068]     At block  1008 , the routine  1000  provides a reply to the homeowner/future home buyer who submitted the request form  1100 . For example, with respect to the components of  FIG. 1 , the notification process  128  may send a thank you email message to a homeowner based on the email field in the request form  1100 . The email message may acknowledge receipt of the request form  1100  and thank the homeowner for submitting such a request, as well as provide additional information such as when he or she may expect to receive a response.  
         [0069]     At block  1010 , the routine  1000  forwards the request form  1100  to the identified agent and notifies the identified agent. For example, with respect to the components of  FIG. 1 , the notification process  128  of the intermediary facility  108  may automatically create an email message or other notification for the agent computer  112  of the identified agent, and send such message over the Web  106 . In some embodiments, the notification process  128  provides not only email notification to the identified real estate professional, but also notification messages via wireless communication devices. For example, under such an embodiment, the notification process  128  provides a notification message to a telecommunications interface. The telecommunications interface, in turn, provides a notification message to a cellular phone (e.g., in the form of a prerecorded audio message), or to a pager (e.g., in the form of an alphanumeric text message). The prerecorded audio message and/or alphanumeric text message inform the identified real estate professional that he or she has a pending request from a homeowner for a comparable market analysis (“CMA”).  
         [0070]     At block  1012  (which applies primarily to the case where a home seller has submitted a request), the routine  1000  receives valuation data from the real estate professional who has completed a comparable market analysis to estimate a selling price for the home identified in the form. For example, this comparable market analysis may be based on local knowledge, data from the homeowner&#39;s completed request form  1100 , and data collected from multiple listing services.  FIG. 12  shows an example of a comparable market analysis form  1200 . The various fields of the comparable market analysis form  1200  are generally self-explanatory. For example, header fields  1202  include the assigned real estate professional&#39;s name, homeowner&#39;s name, submission date and address, which in  FIG. 12  are “Jon Washburn,” “Mark Powers,” “1/1/00,” and “2011 182nd Avenue N.E., Redmond, Wash. 98052,” respectively. An introduction field  1204  may allow the real estate professional to personalize an introductory message to be included in a home evaluation web page that the system makes available to the homeowner (as described below). Recent comparable sales fields  1206  provide four rows of input fields for the real estate professional to list up to four comparable recently sold homes. Data to be completed in the fields include address, square footage, bedrooms, bathrooms, year built, sold price, and comments. Estimated selling price fields  1208  provide low and high estimated selling price fields for the real estate professional to fill in based on the recent comparable sales fields  1206 . A comments field  1210  may allow the real estate professional to add some additional comments regarding the estimated selling price. A closing comments field  1212  may allow the real estate professional to provide some additional information regarding the selling prices and home sales and provide personalized closing text for the home evaluation web page noted below. The comparable market analysis form  1200  also includes four buttons. An update button  1214  may allow the real estate professional, after clicking the button, to update the homeowner&#39;s profile (described below). A help button  1216  may allow the real estate professional to access help instructions stored in the appropriate database or otherwise contact technical support. A preview CMA button  1218  may allow the real estate professional to view a preview of the home evaluation web page, while a send CMA button  1220  sends the completed market analysis form  1200 . After completing the form  1200 , the identified real estate professional clicks the send CMA button  1220 , at which time the real estate professional computer, such as the agent computer  112  of  FIG. 1 , transmits the completed market analysis form  1200  to the intermediary facility  108  to be stored in the database  120 .  
         [0071]     At block  1014 , the routine  1000  stores the received market analysis form  1200  in the appropriate database and creates a home evaluation web page for the homeowner based on the received (and stored) market analysis form  1200 . An example of a home evaluation web page  1300  is shown in  FIG. 13 . Again, the home evaluation web page  1300  is generally self-explanatory. A central section  1302  may include most of the information that the real estate professional input to the comparable market analysis form  1200  (e.g., homeowner&#39;s name and address from the header fields  1202 , text from the introduction field  1204 , the recent comparable sales fields  1206 , estimated selling price fields  1208 , comments field  1210 , and closing comments field  1212 ). The central section  1302  may also include all of the comparable market analysis data requested by the homeowner, and may provide this data in a personalized manner to the homeowner as if from the real estate professional directly. The home evaluation web page  1300  may also include a frame section  1304  that provides a profile and introduction of the identified real estate professional. The frame section  1304  includes a bitmapped image portion  1306  displaying an image of the real estate professional, together with several links to the real estate professional&#39;s web site. A biography or information link  1308  may allow a homeowner to link from the home evaluation web page  1300  to a web page describing the real estate professional&#39;s marketing services, current house listings, and other information about the real estate professional. An email link  1310  may allow a homeowner to quickly and efficiently send the real estate professional an email. A web site link  1312  may allow a homeowner to access the real estate professional&#39;s customized web site. The frame section  1304  also includes one or more banner advertisements  1314  that display advertisements to further generate revenue for the intermediary facility operator.  
         [0072]     At block  1016 , the routine  1000  provides an email message or other notification to the homeowner identifying, and providing a link to, the created home evaluation web page. For example, with reference to the components of  FIG. 1 , the notification process  128  may send a notification email message to the homeowner in a manner similar to the email notification described at block  1008 . The email notification includes a URL link to the created home evaluation web page.  
         [0073]     After the routine  1000  ends, other activities may take place. For example, with respect to the component of  FIG. 1 , the intermediary facility  108  and database manager component  124  of  FIG. 1  may update the identified real estate professional&#39;s contact management data in the database  120 . An example of a contact management web page  1400  is shown in  FIG. 14A . Again, the contact management web page  1400  is generally self-explanatory. Header fields  1402  include the real estate professional&#39;s name, company, address, phone number, email address, and designation of a second real estate professional, if applicable. A pending CMA request section  1404  includes one or more rows of pending CMA requests, with each row including a last name, address, zip code, and two buttons or links  1403  and  1405  to permit the real estate professional to review a pending CMA request and to prepare a CMA, respectively. A pending listing prospects section  1406  includes lists of leads or prospects for which a CMA (home evaluation web page) has been completed. Each row contains many of the same fields as that for the pending CMA request section  1404 , except that a link is not provided to prepare a CMA (because one has already been prepared) but does include a “Contact Now” field to notify the real estate professional that a pending lead should be contacted.  
         [0074]     Referring to  FIG. 14B , the profile web page  1450  may include detailed information with respect to each lead in the real estate professional&#39;s contact management system. As shown in  FIG. 14B , a header section  1452  may include much of the data from fields in a completed web page form. An update homeowner data button  1456  may allow the real estate professional, when clicking thereon, to update the information in the header section  1452 . An email prospect button  1458  may allow the real estate professional to quickly and efficiently send an email to the lead whose profile web page  1450  is currently open. A call button  1460  and schedule an activity button  1462  allow the real estate professional to automatically schedule a reminder for a telephone call or follow-up activity, respectively, with the lead whose profile web page  1450  is currently open. A pending activity field  1464  lists a call or activity scheduled by the button  1460  or  1462 . A comments field  1466  may allow the real estate professional to input comments based on a call or activity with a lead, while a save button  1468  may allow the real estate professional to save such comments. A previous notes field  1470  displays comments previously saved by the real estate professional. A view CMA button  1472  causes the web page manager component  122  to display a home evaluation web page for the current lead, while a delete button  1474  may allow the real estate professional to delete the profile web page  1450  for the current lead.  
         [0075]     In the illustrated embodiment, the contact management web page  1400  and profile web page  1450  may permit the identified real estate professional to identify all pending leads or contacts (homeowners who have submitted a completed request form); data on past contacts/homeowners; agent notes covering conversations or other transactions with contacts, sellers, or homeowners; calendar scheduling information to plan future contacts; and assign an outcome to each lead such as listed and sold, listed with another real estate professional, sold for sale by owner, not planning to sell, etc., and then allow the deletion of a lead.
