摘要：The Mesoamerican region stretches from southern Yucatan, Mexico through Panama. In 1999, the University of Maine, NASA -Global Hydrology and Climate Center and NASA - Jet Propulsion Lab teamed with the Central American Commission on Environment and Development (CCAD), representing natural resources ministries from seven Central American countries, to initiate land cover/land use change research in the region. The NASA/CCAD Memorandum of Understanding enveloping the research program is focused on improving regional monitoring and analysis of environmental condition of the Mesoamerica Biological Corridor. The paper addresses the development of a regional monitoring system using multi-scale and multi-temporal MODIS and Landsat-TM data. A composite, mosaic MODIS data set was compiled from 250 m imagery collected in the 2001-2002 dry season (January – April). The MODIS data was classified into forest and other level 1 cover types using validated forest cover maps developed from Landsat-TM classifications covering 25% of the region. Results of the MODIS forest mapping are discussed. Comparisons of forest cover, forest change, and forest fragmentation between M ODIS and TM data sets, focused on the protected areas of the Mesoamerican Biological Corridor, sheds some light on the feasibility of MODIS for regional forest monitoring
