Introduction to The National Map


As one of the cornerstones of the U.S. Geological Survey's (USGS) National Geospatial Program, The National Map is a collaborative effort among the USGS and other Federal, State, and local partners to improve and deliver topographic information for the Nation. It has many uses ranging from recreation to scientific analysis to emergency response. The National Map is easily accessible for display on the Web, as products and services, and as downloadable data. The geographic information available from The National Map includes orthoimagery (aerial photographs), elevation, geographic names, hydrography, boundaries, transportation, structures, and land cover. Other types of geographic information can be added within the viewer or brought in with The National Map data into a Geographic Information System to create specific types of maps or map views. The National Map is a significant contribution to the National Spatial Data Infrastructure (NSDI) and currently is being transformed to better serve the geospatial community by providing high quality, integrated geospatial data and improved products and services including new generation digital topographic maps.  In addition to being an important contribution to the NSDI, The National Map is foundational to implementation of the Department of the Interior (DOI) Geospatial Modernization Blueprint and meeting the DOI mission to protect America's treasures for future generations, provide access to our nation's natural and cultural heritage, offer recreation opportunities, honor our trust responsibilities, conduct scientific research, provide wise stewardship of energy and mineral resources, foster sound use of land and water resources, and conserve and protect fish and wildlife. The National Map also underpins the USGS Science Strategy which is based on a systems approach to help address multi-faceted issues, provide better understanding of earth processes and evaluate broad causes and consequences of the use and management of natural resources.
This is a new version of The National Map web site.  The site will continue to undergo revisions and we welcome your suggestions and comments to improve this site.

You Can Contribute to National Mapping:
This April marks the one year anniversary of the USGS's The National Map Corps (TNMCorps) transition from a small regional pilot project in the heart of Denver, Colo., into a very successful nation-wide project. During the past year, civilian volunteers in every state have increasingly provided accurate mapping data to the The National Map. Some numbers: 1,422 volunteers; 33,698 points edited; 18 volunteers who have earned more than 500 points. Earn points, get badges! http://on.doi.gov/1heH7y1

    Thumbnail image of US Topo available from the Google Map Gallery. height=73 US Topo maps on Google: USGS National Geospatial Program Director Mark DeMulder, in a guest blog on the Google Enterprise website, announced that the Google Maps Gallery is now featuring US Topo maps. The interactive map allows the user to pick a location and select the desired quadrangles. The quads are downloaded directly from the USGS in GeoPDF format and can be manipulated using freely provided commercial mapping tools. The USGS is working with Google to make sure the application points to the most up to date versions of the maps. http://bit.ly/1rKroQo

    Thumbnail image of Moab, UT 2014 topographic map. height=73 Latest Utah Quads Available: More than 1,475 newly revised US Topo maps for Utah have been posted to the USGS Map Locator & Downloader and accessible through The National Map viewer. The revised maps feature new road data from Nokia. The new maps also include Public Land Survey System (PLSS) data. The PLSS is a way of subdividing and describing land in the United States. All lands in the public domain are subject to subdivision by this rectangular system of surveys, which is regulated by the U.S. Department of the Interior. Other selected states will begin getting the new transportation and PLSS map data during their next respective revision cycle. http://on.doi.gov/1nX4buM

    Thumbnail image of Missouri 3DEP fact sheet. height=73 KY, ME, MO, MT, OR & TN 3DEP Fact Sheets: Increasing the pace of production, he 3D Elevation Program or 3DEP has added six more states to its rapidly growing selection of state-specific fact sheets that features the applications, benefits, and examples of 3DEP.  This data is critical in such fields as agriculture, precision farming, natural resources conservation, flood risk management, infrastructure and construction management, water supply and quality, and other business uses. The Kentucky 3DEP Fact Sheet, the Maine 3DEP Fact Sheet, the Missouri 3DEP Fact Sheet, the Montana 3DEP Fact Sheet, the Oregon 3DEP Fact Sheet, and the Tennessee 3DEP Fact Sheet join the mounting list of 21 state Fact Sheets. All are available for viewing and download from The National Map website.

The new series features 10 topographic maps of the Moab, Utah area. These flash thumbnails of original scanned maps display all available versions of the Moab quadrangles from 1885 to the present in an animated format. The display allows the user to view the maps in chronological order, access larger version of the map and go directly to the download services. http://1.usa.gov/jtRGVx, http://1.usa.gov/HgbHNw [/t][/t][/t]
