## Disciplines of the U.S. Geological Survey

- Biological Resources
- Geology
- Water Resources
- Geography

## Geography Discipline Liaison roles

- Increase awareness of USGS products and programs
- Foster geodata partnerships, projects, science opportunities w/ Feds, States, Locals
- Provide for data access, viewing, integration
- Work with GIS coordination groups
- Build *The National Map*

## Once-over topographic mapping was an immense feat 
The only national synthesis of geographic content that is
		Comprehensive
		Transjurisdictional
		Border to border and 	coast to coast
Cost of replication today would be $2 to $3 billion

- USGS Topographic Maps

**Notes:**
USGS topographic maps are a national treasure.  It took more than 33 million labor hours to compile first-time map coverage and it would cost at least $2 billion to recreate the roughly 55,000 separate maps.

Although there are some national datasets, such as roads, that are maintained by private firms that are more up-to-date and there are some areas, such as cities, for which more detailed base geographic data are available, USGS topographic maps are the only nationally consistent collection of this information.  This collection exists for all cities, counties, and States.  It is the only synthesis of base geographic information that is complete from border to border and from coast to coast.

## What’s Happening?

**Value is eroding rapidly as maps become increasingly outdated**
**Limited resources affect maintenance**
**The maps and digital data do not correspond**
**Duplication of effort is emphasizing the  need to share**
**National priorities are demanding current information**

**USGS 1953; PR 1966 & 1974**

**Pixxures 2000**

**Baltimore, MD**

**Notes:**
Unfortunately, traditional approaches to topographic mapping have not enabled the USGS to maintain the currentness of the topographic maps.  The average age of USGS topographic maps is about 23 years.  The usefulness of this massive collection of vital information is jeopardized.

This is clearly shown in Baltimore, Maryland. The current USGS map was photorevised in 1974.  However, a recent orthoimage shows interstate highway and sports stadium construction and urban redevelopment around Baltimore’s Inner Harbor.  Although the orthoimage is a valuable record of the landscape, the integrated data shown on the map provide content that is not available on the image, such as feature classifications, elevation, boundaries, and geographic names.

Because USGS topographic data programs exists independently of topographic map revision, the content of the digital datasets and the corresponding topographic maps often do not match.  And because State and local governments and the private sector also produce geographic data, there are redundant and sometimes conflicting datasets.  The Nation needs consistent, current, and immediately available base geographic data.

## Value of Topographic Information

**Foundation for economic enterprise**
**Essential for efficient delivery of government services **
**Key to effective land and resource management**
**Critical for ****homeland security**

## First Step - A New Vision

***Maintained through****** partnerships ***
***A national foundation ******for science, land and resource management, recreation, policy making, and homeland security****** ***
***Available over the Web – 24/7 - ******and the****** source for revised topographic maps***

**First Step - A New Vision**

**Notes:**
“The National Map” is the name given to the multi-sector, integrated, responsive geographic base data and map program for topographic information.

The National Map will be a seamless, continuously maintained, and nationally consistent set of public domain base data.  These are characteristics that our data partners and users tell us are important.

We will maintain the currentness of The National Map by establishing partnerships for data maintenance with State and local governments and the private sector.

The National Map data will be the source for updated topographic maps to greatly improve the currentness of these traditional products.

## Second Step – Refocusing the Geography Discipline

**Second Step – Refocusing the Geography Discipline**

**Transition from “mapping” to “geography”**
**Brings the full spectrum of geographic science to bear on key national issues and needs**

** ****Map           Monitor             Understand             Model           Predict**

*The National Map*

**Notes:**
The data content of The National Map will meet broad user requirements for a public domain foundation of geographic information.

Orthorectified (scale corrected) imagery is a key source of interpreted feature information for The National Map, and is an archive medium in its own right for portraying data that do not lend themselves to extraction and symbolization.  Imagery will come from a variety of sources, including aerial photography and commercial remote sensing satellites.  Private firms now have licenses to collect high-resolution satellite data, at 1 meter and even .5 meter ground resolution. In addition, The National Map will serve seamless Landsat satellite imagery to provide intermediate-resolution national coverage.  Image data will underpin The National Map and give us an accurate and current base to work from.

Land cover data classify the land surface into categories such as open water, perennial ice and snow, evergreen forest, and high-density residential.  These data are key to scientific studies and to business and government operations.  Users want land cover data to be integrated with other USGS products.

## The National Map:  Data Content

**Orthorectified imagery**

**Land characterization**

**Elevation**

**Vector layers:**
**Transportation**
**Hydrography**
**Structures**
**Boundaries**

**Geographic names**

**Notes:**
Consider the reality of what USGS does now and what we propose to do for the future.  The data content of the National Map will meet broad user requirements for a foundation of geographic information.

Orthorectified (scale corrected) imagery is a key source of interpreted feature information for The National Map, and is an archive medium in its own right for portraying data that does not lend itself to extraction and symbolization.  Imagery comes from a variety of sources now, including the commercial satellite remote sensing business that is being built.  There are debates about whether or not this industry will be successful, but the fact is that private firms now have licenses to collect high-resolution satellite data, at 1 meter and even .5 meter ground resolution.  And whether it’s today’s business model or some other business model, we believe that there is going to be widely available high resolution imagery from satellites and other sources well within the 2010 time frame.  Image data will underpin the National Map and give us an accurate and current base to work from.

The reVision 2010 team heard time and again that land characterization data is key to scientific studies and to business and government operations.  Users want land characterization data to be integrated with the other products that they also use from the USGS.
