Maps
Our programs produce accurate geologic maps and 3-D geologic frameworks that provide critical data for sustaining and improving the quality of life and economic vitality of the Nation. They also organize, maintain, and publish the geospatial baseline of the Nation's topography, natural landscape, built environment and more.
The 3D Elevation Program: Understanding Natural Hazards in Three Dimensions
This story map provides an overview of the 3D Elevation Program (3DEP) and highlights how lidar data support hazards applications for volcanoes, earthquakes, landslides, hurricanes, flooding, drought and wildfires. An assessment of 3DEP data coverage as of December 2018 for high-risk areas of landslides, fires and hurricanes is presented.

Elevation Data
The 3DEP products and services available through The National Map consist of 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.
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.
Download Topographic Maps from the National Map
This is the primary search and download application for USGS topographic maps and base-layer GIS data. The same topographic maps are also downloadable through other interfaces.
The National Map Viewer
The National Geospatial Program satisfies the needs of customers by providing geospatial products and services that customers incorporate into their decisionmaking and operational activities.
Alaska Mapping
New US Topo maps for Alaska are being produced statewide, with digital 7.5 minute 1:25,000-scale maps providing a comprehensive update to the 15-minute 1:63,360-scale printed maps produced nearly fifty years ago. You can view a status map showing where the new maps are available, and link to a site to download the maps.
