The National Map

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.

Alaska IfSAR Elevation Data

Radar data is being collected statewide for Alaska under direction of the USGS 3D Elevation Program (3DEP). The new data is vastly improving the accuracy and resolution of elevation data for the state, and is being collected using an airborne Interferometric Synthetic Aperture Radar (IfSAR) sensor. USGS and the State of Alaska maintain web-based status maps and download services.

Transportation Data

The transportation data theme consists of roads, airports, railroads, and features associated with the transport of people or commerce. The data includes the location, classification, name/route designator, for most roads, and address ranges. The data supports mapping and geographic analysis for applications for routing, traffic safety, congestion mitigation, and disaster planning and response...

Structures Data

USGS data portray selected structures data, including the location and characteristics of manmade facilities. Characteristics consist of a structure's physical form (footprint), function, name, location, and detailed information about the structure. The types of structures collected are largely determined by the needs of the disaster planning and response and homeland security organizations....

The United States Interagency Elevation Inventory (USIEI)

The USIEI is a comprehensive, nationwide listing of known high-accuracy topographic and bathymetric data for the United States and its territories. The project is a collaborative effort of the USGS and NOAA with contributions from other federal agencies. The inventory supports the 3D Elevation Program and the Integrated Ocean and Coastal Mapping effort. This resource is updated in Spring and...

Elevation Data

The 3DEP products and services available through The National Map consist of lidar point clouds (LPC), standard digital elevation models (DEMs) at various horizontal resolutions, elevation source and associated datasets, an elevation point query service and bulk point query service. All 3DEP products are available, free of charge and without use restrictions.

Orthoimagery Data

Orthoimagery data typically are high resolution aerial images that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a planimetric map. The National Map offers public domain, 1-meter orthoimagery for the conterminous United States with many urban areas and other locations at 2-foot or finer resolution.

The National Map Small-Scale Collection

The National Map offers a collection of small-scale datasets, most of which are at 1:1,000,000. The National Map publishes two data collections at one million-scale: one for Global Map users and one for National Map users. In terms of vector geometry, the lines, points, and areas in these data collections are identical. The difference is in the attributes assigned to these features.
