End users search the GOS catalog to find the data they need

## Geospatial One-Stop User Benefits

- Government agencies reduce project costs by:
- reusing existing data
- identifying partners for spatial data acquisition projects
- Public and Private geospatial data providers expose their data and services to end users by publishing metadata to Geospatial One-Stop
- Geospatial data end users can locate available geospatial data resources and services

## The GOS Portal – www.geodata.gov

- Requires only an Internet Browser for access
- No Special Software needed

- The Geospatial One-Stop Website (_[www.geodata.gov](http://www.geodata.gov/)__ )_

**Notes:**
www.geodata.gov is the web site (portal) for the Geospatial One-Stop
The GOS website (www.geodata.gov) is accessed using a Web Browser.  No special software is needed.

## Functional Areas in the Portal

**Search** – enables users to find geospatial data
**Communities **– highlight authoritative data sources
**Featured Resources** – highlight maps, applications and websites of current interest

**Notes:**
The GOS Portal has several functional areas including:
A search portlet that lets users search for, find and obtain geospatial data
A Communities list where a user can browse for key geospatial resources by topic 
A featured topic area where current events or topics are emphasized

## The Geodata.gov Map Viewer

- Geospatial data can be previewed in the Map Viewer
- Data from different data sources (Web Mapping Services) can be overlain

**Notes:**
The GOS portal includes a Map Viewer where live data and maps (Web Mapping Services) can be added to a map

## The Role of Geospatial One-Stop Metadata

- Metadata Describes Data
- Publishing metadata to Geospatial One-Stop enables data to be discovered
- Geospatial One-Stop metadata provides links to data
*Data providers publish individual metadata records for each data set, map product, web mapping service, or other geospatial data resource.*

## Types of Information in a Metadata Record

- Title and Author
- Publication Date and Status
- Abstract, Summary, and Purpose
- Full Content Description
- Spatial Domain
- Keywords
- Access and Usage Information
- Other Reference Information per Metadata Standards

## Metadata Format and Content Standards

- Geospatial One-Stop requires metadata that is formatted as specified by the FGDC’s *Content Standard for Digital Geospatial Metadata* (CSDGM)
- For more information about geospatial metadata standards visit:
- _[www.fgdc.gov/metadata/geospatial-metadata-standards](http://www.fgdc.gov/metadata/geospatial-metadata-standards)_

## Types of Information in Geospatial One-Stop 

- Live Data and Maps
- Streaming Web Mapping Services (WMS) that can be loaded into the Geospatial One-Stop Map Viewer
-  Downloadable Data
- Data sets that can be downloaded and used in your local GIS
-  Offline Data
- Data that is available but must be obtained by contacting the publisher identified in the metadata record
-  Documents
- Geographic information stored in text files, spreadsheets, or other documents

## Types of Information in Geospatial One-Stop

**  ****Obtain Data (conditional)**

## Conduct Basic Search

**Enter a Keyword in the “What” field (Text Search)**
**Enter a Location in the “Where” field (Geographic Search) to narrow your results**

## Conduct Advanced Search

**Notes:**
In the Search portlet or Search tab, click on the Show Advanced Search Options link to see more search criteria.
In addition to the What and Where values you can select data by timeframe, Content Type, and Data Category.
You can also use the My Geography map to define a spatial area for a search.  The Spatial search can allow data to overlap the area of interest or lie within the area of interest for a more specific search.
Results can be sorted by several criteria such as relevance, date, title and smallest or largest coverage area.
These features are covered in more detail in the next module.

## View Search Results

- Depending on the type of data found, you can:
- View a summary of the metadata
- View full metadata,
- Add data to a map (If it is available through a Web Mapping Service)
- Go to a Website where more information can be found or from which the data can be obtained
- Download the data

## View (Metadata Details) Summary

**	****“***View Summary” provides more metadata detail than is displayed in the initial search result*

- The metadata summary includes a graphic that shows the area of coverage for the data set.

## When the “Full Metadata” option is selected, the data publisher’s complete metadata record is displayed

- View Full Metadata

## Add to Map

*If the Content Type in the metadata is “Live Data or Map Service,” you can view the cited mapped data in the Geospatial One-Stop Map Viewer by selecting the “Add to Map” option*

**Notes:**
