It has many uses ranging from recreation to scientific analysis to emergency response. Viewer Viewer (TNM Viewer) is the one-stop destination for visualizing all the latest National Map data. It uses easy to navigate foundational base maps and makes it simple to interact with all our data themes to create your own map. Let's make MY MAP! TNM Training courses offers you Video training courses to help you learn all you can do with . Access Training Liaisons (TNM) Liaisons partnership network cultivates and maintains long-term relationships with partners and develops agreements for and other initiatives that support USGS science. Contact Us is a suite of products and services that provide access to base geospatial information to describe the landscape of the United States and its territories. embodies 11 primary products and services and numerous applications and ancillary services. supports data download, digital and print versions of topographic maps, geospatial data services, and online viewing. Customers can use geospatial data and maps to enhance their recreational experience, make life-saving decisions, support scientific missions, and for countless other activities. Nationally consistent geospatial data from enable better policy and land management decisions and the effective enforcement of regulatory responsibilities. is easily accessible for display on the Web through such products as topographic maps and services and as downloadable data. The geographic information available from includes boundaries, elevation, geographic names, hydrography, land cover, orthoimagery, structures, and transportation. The majority of effort is devoted to acquiring and integrating medium-scale (nominally 1:24,000 scale) geospatial data for the eight base layers from a variety of sources and providing access to the resulting seamless coverages of geospatial data. also serves as the source of base mapping information for derived cartographic products, including 1:24,000 scale US Topo maps and georeferenced digital files of scanned historic topographic maps. Data sets and products from are intended for use by government, industry, and academia—focusing on geographic information system (GIS) users—as well as the public, especially in support of recreation activities. Other types of georeferenced or mapping information can be added within Viewer or brought in with data into a GIS to create specific types of maps or map views and (or) to perform modeling or analyses. Use and Download our Data and MAPS! National Map GIS data download and other related applications for working with our topographic data are available on our Data Delivery site. Themes (TNM) supporting themes include boundaries, elevation, geographic names, hydrography, land cover, orthoimagery, structures, and transportation. Other types of georeferenced or mapping information can be added within TNM Viewer or brought in with TNM data into a GIS to create specific types of maps or map views and (or) to perform modeling or analyses. 3D Elevation Program The 3D Elevation Program (3DEP) is managed by the USGS National Geospatial Program on behalf of the broader community with a goal of complete acquisition of nationwide lidar (IfSAR in AK) in 8 years to provide the first-ever national baseline of consistent high-resolution elevation data – both bare earth and 3D point clouds – collected in a time-frame of less than a decade. We also continue to be ready to meet growing needs for higher quality data, repeat coverage, and new products and services. These data serve government, public and private sector needs for a wide range of activities that include flood hazard mapping, precision agriculture, infrastructure planning and development, natural resource management, environmental assessment and a host of other applications. Corps NMCorps is an online crowdsourcing mapping project with volunteers successfully editing structures in all 50 States, Puerto Rico, and the U.S. Virgin Islands. As part of , structures include schools, hospitals, post offices, police stations, cemeteries, and other important public buildings. By updating and verifying structures data, volunteers ...
