Classification of Land-Cover Types for the Fort Benning Ecoregion Using Enhanced Thematic Mapper Data

摘要

Information regarding regional land cover is a fundamental requirement to support the long-term baseline ecosystem monitoring plan under the Strategic Environmental Research and Development Program (SERDP), Ecosystem Management Project (SEMP), Ecosystem Characterization and Monitoring Initiative (ECMI). The land cover characterization phase of this plan provides the foundation needed to derive vegetation density indices and land cover patterns. These characteristics are the primary visible expressions of the underlying ecosystem structure, function, and process at all spatial scales (Kress 2000). To meet the requirement for land cover information, Landsat 7 Enhanced Thematic Mapper (ETM) data were used to classify land cover types for the Fort Benning ecoregion. This technical note (TN) describes the procedures used to extract land cover information from the satellite imagery.
