Geospatial Data

U.S. Forest Service - National Geospatial Data

The USDA Forest Service Geodata Clearinghouse is an online collection of digital data related to forest resources. Through the Clearinghouse you can find GIS datasets related to forests and grasslands, including boundaries and ownership, natural resources, roads and trails, as well as datasets related to State and private forested areas, including insect and disease threat and surface water importance. You can also find downloadable map products, raster data, and links to other sources of forest resource information.

For KML and other file formats visit the Forest Service Geospatial Data Discovery page. This ArcGIS Online data hub has many current Forest Service GIS data layers. The U.S. Forest Service has configured this open data site to help our partners and the public discover geospatial data published by the Agency. Use it together with your data to create maps, apps and other information products. Need a tour?

Region One VMap

The R1 VMap geospatial database relates vegetation attributes to spatially unique polygons, or delineations, of vegetation patterns. The VMap database provides four primary map products; lifeform, tree canopy cover class, tree size class, and tree dominance type to support mid and base-level analysis and planning. VMap uses the Region 1 Existing Vegetation Classification System (R1-ExVeg) (Barber, et.al. 2009) in its map unit design.

VMap is a remote sensing derived product. As such, it uses a combination of high resolution airborne imagery and a nationally available digital elevation model (DEM)
