USGS Geospatial Data Sources


Primary Sources of FREE USGS Geospatial Data

The National Map
Go to The National Map Download Client to download US Topo and historical topographic maps, and data for the United States for various themes to include: 1) Boundaries; 2) Elevation Products (3DEP); 3) Elevation Source Data (3DEP); 4) Hydrography (NHD) and Watersheds (WBD); 5) Imagery from High Resolution Orthoimagery and National Agriculture Imagery Program; 6) Map Indices; 7) Geographic Names; 8) Land Cover; 9) Structures; 10) Transportation; and 11) Woodland. Contours are under Elevation Products, and lidar point clouds are under Elevation Source Data.
 
Small-scale data, formerly on The National Atlas, includes Printable Maps, Small-scale Framework data, and Global Map data (1:1,000,000 scale).
 
The National Map Services provide a complete list of service endpoints, which contain REST, WMS, WMTS (cached base maps only), WFS, WCS, and other service links.
Earth Explorer*
Download data from more than 300 data collections that span over 75 years of coverage. Includes USGS satellite imagery, historical and recent USGS aerial photography, elevation data, land cover products, Lidar point cloud data, Digital Line Graphs (DLGs), Digital Orthophoto Quads (DOQs), and much more. How to use Landsat Spectral Bands can be helpful.
GloVis*
Just looking for satellite imagery? Don't really need a robust and complex search engine? GloVis is a browse-based viewer that's easier to search and more user-friendly than EarthExplorer. Products include Landsat, ASTER, EO-1, MODIS, and TerraLook imagery, NAPP and NHAP imagery. How to use Landsat Spectral Bands can be helpful.

Additional FREE Geospatial Data from the USGS & Our Partners

TerraLook*
Georeferenced Landsat and Aster satellite images in JPEG format for users who don’t want to use complicated software. Perfect for simple visual interpretation and to track changes over time. Download optional free software for very basic manipulations. The Landsat images are preselected for best views.
LandsatLook*
Full-resolution JPEGs of Landsat satellite images that are best used for image selection and simple visual interpretation. Available as thermal or natural color images with optional geographic reference. Not recommended for digital analysis.
Data.gov*
Geospatial information from all levels of government and the public.
National Geologic Map Database
Search over 90,000 maps and reports, including free digital maps and GIS map data. Primary themes are geology, geophysics, marine, energy resources, and natural hazards.
Hazards Data Distribution System (HDDS)*
A dynamic online map interface that can be used to view and download USGS datasets for national or international disasters including floods, hurricanes, tsunamis, and earthquakes.
Water Spatial Data
Maps and GIS data for water related topics such as water use maps and data, watershed boundaries, NHD, streamflow records, and more.
USGS Quaternary Fault and Fold Database
Geologic, geomorphic, and geographic information for over 2,000 Quaternary (active in the last 1,600,000 years) faults in the U.S. Download shape files and Google Earth files.
Mineral Resources On-Line Spatial Data*
A source for regional and global geology, geochemistry, geophysics, and mineral resource maps and data. Includes map services.
Global Mineral Resource Assessments*
Most of these reports contain GIS data. The USGS is in the process of compiling all the data in a single location, but for now users must review each link.
Energy Data Finder*
Geospatial data related to oil & gas, coal, geochemistry, and geophysics. This is also a good place to look for base data in international locations (used in global energy assessments).
Maps of America’s Submerged Lands
A portal to published USGS maps, reports, and digital data that depict the bathymetry, surficial geology, and/or subsurface structure of selected submerged U.S. areas. This mostly coastal locations, but includes some lakes.
Coastal & Marine Interactive Map Server
GIS data and metadata for past and current projects.

FREE Bulk Downloads of Maps and Geospatial Data

The National Map Bulk Download Applications
Start with this application if you need less than an entire hard drive of data. Includes orthoimagery but not satellite imagery.
National Hydrography Dataset (NHD)
Full national coverage of the NHD is available on DVDs. This includes all medium-resolution and high-resolution (where available) data. To request the DVDs, please send 1) the desired format (or both formats if preferred), and 2) your mailing address to: nhd@usgs.gov. For additional information, send email to nhd@usgs.gov.
Available formats:

3D Elevation Program (3DEP)
You supply the external hard drive (within our specifications), along with a paid return label for return shipping. Turnaround time is 1-4 weeks. Detailed options and instructions.
Minimum deliveries are for complete datasets of:
 
Orthoimagery, National Land Cover Dataset (NLCD)
You supply the external hard drive (within our specifications), along with a paid return label for return shipping. Turn-around time can take up to 4 to 8 weeks. Detailed options and instructions.
Available data includes:
 
Landsat Imagery, some EarthExplorer Data, Hazards Data Distribution System (HDDS) Imagery
Use the Bulk Data Application (BDA) to download up to 500 individual files after generating a scene list in EarthExplorer (comma separated metadata export), GloVis (saved scene list), or HDDS.

US Topo and Historical Topographic Maps
Bulk delivery by county, state, geographic rectangle (lat/long bounding box), or the entire product series is possible through four mechanisms at no charge. Options 3 and 4 provide means for keeping a private file-set current. Additional information with updated dataset sizes.

  1. Batch Download. For roughly 1,500 or fewer maps (state-size areas): The National Map Download Client allows maps to be selected over any rectangular area, or predefined areas such as counties or states. The resulting product list can be saved to a CSV file, and this file used as input to a Download Manager program to retrieve all the maps. 

    Alternatively, we can email you a custom batch file for one or more states. This batch requires your computer to have the wget utility, which is open source and free. For more details, send a message describing your requirements to tnm_help@usgs.gov. Please include which product(s) (US Topo or HTMC) you want, and the state(s) you need coverge for. This is not general-purpose software, but is a batch file for one or more specific states. This batch is functionally equivalent to the Download Manager option above.

  2. Portable Disk Drive. For more than 1,500 maps (up to the entire map collection): If you ship us a portable disk drive with prepaid return shipping, the USGS will load the drive with maps and return it to you. For more details, send your requirements (including product type and area of interest) to tnm_help@usgs.gov.

    Hard drive shipping is intended for one-time or infrequent deliveries. Users who wish to keep a private collection continuously current are encouraged to use options 3 and 4 to monitor US Topo production and retrieve new maps. We do not have a subscription service for notification of new maps, nor do we coordinate disk-drive deliveries with production milestones; requests for bulk delivery are queued as we receive them and answered as quickly as other work permits.

  3. CSV Database Dump. For advanced users. The data needed to create download scripts is available at US Topo and Historical Topographic Map Collection. This application allows searching for subsets of US Topo and HTMC maps. Search results can be saved to a CSV file, which includes a download URL for each map. (The National Map Download Client has similar features.) In addition, a complete CSV dump of the database is refreshed nightly and posted to the same page. The information in this complete file can be used for more sophisticated filtering, version control, and to keep private collections of maps up to date. This option is for advanced users; we do not provide tutorial assistance.
  4. Catalog API. For skilled web programmers: USGS product databases can be monitored through the API of the ScienceBase catalog. This is similar to option 3, but is more elegant and powerful. See https://my.usgs.gov/confluence/display/sciencebase/ScienceBase for documentation. This option is for skilled web programmers.
