Description:
Abstract:
Vegetation and land cover information were derived from classified Landsat TM satellite imagery obtained in 1993 and 1994. Training data included vegetation points identified from aerial videography flights. Ancillary data used in classification and in final data set (in some cases) includes National Wetlands Inventory data, USGS DLG roads data, and EPA MRLC land use/land cover data.
Purpose:
This dataset serves as a key input to the West Virginia Gap Analysis vertebrate wildlife distribution modeling process. Gap Analysis is a broad-scale conservation effort focused on identifying wildlife habitats and species under-represented in current conservation lands.
Supplemental_Information: See WV-GAP Final Report for more details.

Process_Description:
Land cover was mapped from Landsat TM imagery using methods described in Yuill et. al (forthcoming).

Spatial_Data_Organization_Information:
Indirect_Spatial_Reference:
Landsat Thematic Mapper scenes were registered to locations identified on 1:24,000 and 1:100,000 scale USGS topographic maps. National Wetlands Inventory data for West Virginia (1:24,000 scale) were also obtained from the US Fish and Wildlife Service.
