Mapping and GIS Development of Land Use and Land Cover Categories for theAlbemarle-Pamlico Drainage Basin

摘要

The Albemarle-Pamlico (A/P) estuarine system in North Carolina is one of theestuaries in the EPA's National Estuary Program. At an A/P Study workshop held late in 1987, Landsat Thematic Mapper (TM) digital data were recommended as the most cost effective and practical source for developing an inventory for the 23,000 square mile drainage basin. The study area included a portion of Virginia and nearly one-third of North Carolina including almost all of the Tidewater region. Results of the project included image files in raster format with every pixel classified by land use/land cover category. Classification verification was performed using 1,931 one acre sample sites located on the classified TM imagery and on aerial photography. Land use/land cover data are available from CGIA as map products or in digital format. Final results also include descriptions of methodology and land use/land cover classes as well as classification error matrices for each physiological province and for the entire study area.
