Southwest Regional Gap Analysis Project
'PROVISIONAL' Landcover and Related Datasets


The Southwest Regional Gap Analysis Project (SWReGAP) was initiated in 1999 as a multi-institutional cooperative effort to map and assess biodiversity for a five-state region (AZ, CO, NV, NM, UT) comprising approximately 560,000 square miles in the southwestern U.S.

A key task was the development of a seamless landcover map for the region and the collection of other pertinent bio-physical spatial data. Through coordination from the U.S. Geological Survey’s Gap Analysis Program (GAP) and the collaborative efforts of participating state institutions, a seamless landcover product was completed in September 2004. These data and related datasets are made available to the public with ‘provisional’ status by the SWReGAP consortium of institutions responsible for their development. Following a peer review process meeting USGS GAP requirements, these data will be provided with ‘final’ status.
