GIS Coverages

The San Juan National Forest operates a Geographic Information System (GIS). We use ESRI's ArcGis family of products to develop various maps of the forest and to perform analysis. Data can be made available upon request. Most of the data contained in the compressed ZIP files is in GeoDataBase (MDB) format. We are in the process of replacing all of the coverages with GeoDataBases. ArcGis software 9.0 or better is required to use this data.

File Compression Notes

The files to download are compressed with WINZIP. Each compressed file contains an ArcGis personal Geodatabase (MDB). The GeoDataBases contain metadata that may be viewed using the ArcCatalog metadata tool.
