Notes

Southeast Gap Analysis Project, 1999–2001 "The digital land cover dataset may be used for various purposes with user's discretion. Specifically, this dataset was created for regional terrestrial biodiversity assessment. These data are not intended to be used at scales larger than 1:100,000." (metadata.xml)

Application

"The Mission of the Southeast Gap Analysis Project (SE-GAP) is to provide data and assistance for regional assessments of the conservation status of native vertebrate species and natural land cover types and to facilitate the application of this information to land management activities."

Method

"Multi-season satellite imagery (Landsat ETM+) from 1999-2001 were used in conjunction with digital elevation model (DEM) derived datasets (e.g. elevation, landform) to model natural and semi-natural vegetation. General land cover classes (i.e. water, urban, row crop) were included from the National Land Cover Dataset 2001... The minimum mapping unit for this dataset is 0.4 ha (1 acre). Vegetation classes were drawn from NatureServe's Ecological System Classification... Two hundred fourteen (214) land cover classes… were mapped with a variety of techniques including decision tree classifiers, unsupervised classification, and expert decision rules." (metadata.xml)
