Vector Data
The FSTopo database was originally populated with Cartographic Feature File (CFF) data. CFF data were derived from the standard Forest Service Primary Base Series (PBS) or Single Edition Series (SES) map as part of the National Geographic Information System Plan. PBS and SES maps were developed from the U.S. Geological Survey 7.5-minute topographic map series, with enhancements and regular revisions to satisfy Forest Service needs.
