GAP Land Cover

This raster dataset is a detailed (1-acre minimum), hierarchically organized vegetation cover map produced by computer classification of combined two-season pairs of early-1990s Landsat 4/5 Thematic Mapper (TM) satellite imagery, as part of the Upper Midwest Gap Analysis Program (UMGAP)( http://www.umesc.usgs.gov/reports_publications/psrs/psr_1999_04.html ) of the U.S. Geological Survey. Units of analysis were Minnesota Ecological Classification System (ECS)( http://www.dnr.state.mn.us/ecs/index.html ) subsections subdivided by TM scenes. GAP typology and classification protocols are closely comparable across Minnesota, Wisconsin and Michigan.

dsPurpose The dataset was created for use in the Geological Survey's Gap Analysis Program (GAP)( http://gapanalysis.usgs.gov ) , a national project aimed at prioritizing lands for conservation action. Other uses include stratification of inventories, land use planning, and spatial analysis of landscape patterns.
