USGS is a primary source of Geographic Information Systems (GIS) Data. Our data and information is presented in a spatially and geographically including The National Map, Earth Explorer, GloVIS, LandsatLook, and much more. Start exploring by topic below.
This story map application provides an interactive map showing light trap locations along the Colorado River as well as other content further describing this Citizen Science initiative. Data are currently available for the years 2012 through 2014, with more recent efforts coming soon.
USGS Flood Inundation Maps, along with Internet information regarding current stage from the USGS streamgage, provide emergency management personnel and residents with information that is critical for flood-response activities, such as evacuations and road closures, as well as for post-flood recovery efforts.
The NCGMP is the primary source of funds for the production of geologic maps in the United States and provides accurate geologic maps and three-dimensional framework models that help to sustain and improve the quality of life and economic vitality of the Nation and to mitigate natural hazards. Geologic mapping data from all of North America are presented via the National Geologic Map Database.
This web site is dedicated to providing water-quality load and trend results for the nontidal rivers of the Chesapeake Bay watershed.
These data support the following publication (available online early): Jonathan J. Felis, Michelle L. Kissling, Robb S. A. Kaler, Leah A. Kenney, and Matthew J. Lawonn (2016) Identifying Kittlitz's Murrelet Nesting Habitat in North America at the Landscape Scale. Journal of Fish and Wildlife Management In-Press. doi: http://dx.doi.org/10.3996/112015-JFWM-116.
The survey was conducted in summer 2002 to assess the presence of terrapins in the Maryland portion of the Chesapeake Bay. Results are spatial locations of evidence related to nesting.
USGS has recently undertaken a project to develop a methodology for assessing wind energy impacts on wildlife at a national scale. The USGS data set provides industrial-scale onshore wind turbine locations in the United States through July 22, 2013.
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.
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.
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 National Land Cover Database (NLCD) serves as the definitive Landsat-based, 30-meter resolution, land cover database for the Nation.
Boundaries data or governmental units represent major civil areas including states, counties, Federal, and Native American lands, and incorporated places such as cities and towns.
