Abstract: The North Carolina Center for Geographic Information and Analysis, in cooperation with the NC Department of Transportation and United States Environmental Protection Agency Region IV Wetlands Division, contracted Earth Satellite Corporation (EarthSat) of Rockville, Maryland to generate comprehensive land cover data for the entire state of North Carolina. EarthSat was awarded the base/municipal area deduct contract in response to request for proposal (RFP) number 503768, issued 12 July 1995.
Purpose: These data were created to assist governmental agencies and others in making resource management decisions through the use of a geographic information system (GIS).
Supplemental Information: Twenty-two TM scenes were acquired from EOSAT Landsat Thematic Mapper (TM) and used by EarthSat to produce land cover classification. See full documentation for this data layer in report, "Comprehensive Land Cover Mapping for the State of North Carolina: Final Report," March 1997, Rockville, Maryland: Earth Satellite Corporation. Revisions and updates to this layer include: 1.) Revision date: June 12, 1998 - Removal of a pixel-wide sliver of no data between the Laurinburg and Elizabethtown 100k sheets. The error first occurred during the clipping process of the statewide landcover arc/info grid with the two 100k neatline boundaries. The problem was rectified by clipping the adjoining two 100k's as one grid, vectorizing that grid, and then clipping by each 100k neatline.
