Download National Datasets

Data collected and managed by Forest Service programs is available in a map service and two downloadable file formats – in a shape file and an ESRI file geodatabase. Metadata is available that describes the content, source, and currency of the data. You can filter the list by the topic categories in the menu at the left to help you find information you are interested in. You can view the feature classes in a single dataset by clicking on the name of the parent dataset at the bottom of the abstract.

Shapefile Limitation Warning:
The Enterprise Data Warehouse Team has identified certain technical limitations of shapefiles which make them not suitable for all datasets within this clearinghouse. Due to file size limits as well as attribute name length and field length restrictions leading to inevitable data loss, the EDW Team is unable to support shapefile exports for larger datasets. There are other methods to accessing this data in addition to the Esri File Geodatabase (FGDB) including the map service or the Geospatial Data Discovery Tool.

Requests for KML/KMZ output
The Enterprise Data Warehouse Team tested exporting out to KML/KMZ files as a deliverable and due to the complexity and size of the datasets this has been unsuccessful. To obtain a KML file for any EDW dataset, go to the Geospatial Data Discovery Tool and search for the dataset. An option to download to KML is available from that website.

This dataset includes polygons with a minimum of 40 acres of woodlands per square mile as depicted in William H. Brewer’s 1873 map of woodland density and covers the conterminous United States. Each polygon has been labeled with the density category (1-5) depicted on the original map. This dataset was created by
