GIS Data

Developed by the USGS and several federal agencies, the NLCD provides nationwide data on land cover and land cover change at a 30m resolution with a 16-class legend.

Researchers at the US Geological Survey have used a wide range of historical data sources and a spatially explicit modeling framework to model spatially explicit historical LULC change in the conterminous United States from 1992 back to 1938. Annual LULC maps were produced at 250-m resolution, with 14 LULC classes.

From Global Land Analysis & Discovery, datasets on land cover change from 2000-present. Can explore in their viewer or download the data.

From USGS, access land cover, aerial photographs, various satellite images, and elevation data.

Shows where Lidar data is available, let's you search by area of interest and allows you to download either the Lidar or DEM (digital elevation model) data that covers your area.

Access to aerial photographs, digital elevation models, LiDAR, satellite imagery, the National Satellite Land Remote Sensing Data Archive and land cover data.

The "One Stop Source" for environmental and natural resources data. Choose the area of interest, browse and select data from the catalog, customize the format, and download it.

Links to the agencies in each state with available LiDAR data

Offers aerial imagery, land cover, elevation, administrative boundaries, watersheds, and data from the National Transportation Dataset and the National Structures Dataset

Datasets from USGS reports, includes GIS data on many topics

Soil maps and data available for more than 95 percent of the nation’s counties; the single authoritative source of soil survey information.

Includes the popular National Wetlands Inventory, the Critical Habitat Portal, and other information from Fish and Wildlife Service GIS data sources.

The NHD represents drainage networks with features such as rivers, streams, canals, lakes, ponds, coastline, dams, and stream gages while the WBD shows watershed drainage basins

From the USGS, the one stop shop for water maps and GIS data; groundwater, surface water, water quality, and more.
