LEDAPS

LEDAPS, a NASA-funded project to map North American forest disturbance since 1975 from the Landsat satellite record, produced comprehensive maps of surface reflectance for 1975, 1990, and 2000 for the United States and Canada. LEDAPS was a part of NASA's contribution to the North American Carbon Program (NACP), a component of the USGCRP Carbon Cycle Science Program.
