摘要:The Multi-Resolution Land Characteristics (MRLC) Consortium is a group formed by the U.S. federal agencies in 1990 to purchase Landsat 5 Thematic Mapper imagery for the conterminous U.S. and to develop a National Land Cover Dataset (NLCD 1992). The NLCD 1992 was completed in 2000. In 1999, a second-generation MRLC (MRLC 2001) consortium was formed to purchase three dates of Landsat 7 Thematic Mapper Plus (and some Landsat 5) imagery for the entire United States and to coordinate the production of a comprehensive National Land Cover Database (NLCD 2001). The NLCD 2001 was completed in April 2008.The NLCD 1992 and NLCD 2001 are specifically designed to meet the needs of the U.S. federal agencies for nationally consistent satellite remote sensing and land cover database. In addition, the MRLC consortium provides the database as public domain information. This paper summarizes the philosophy and scientific and technical issues with regard to design and implementation of the NLCD 1992 and NLCD 2001. Experiences and lessons learned from the intensive efforts to develop the two national land cover datasets are documented, including project design, technical approaches, accuracy assessment strategy, and project implementation
