Landsat Pathfinder Program
The goal of the Landsat Pathfinder Program is to establish long-term, medium- to high-resolution data sets for particular regional and global applications to global change research. The Landsat Pathfinder Science Working Group has defined several projects to address land cover change.
The Humid Tropical Forest Project (HTFP) is generating a 3-epoch forest/non-forest data set showing areas of deforestation in the moist tropical forest regions (i.e. the Amazon, Central Africa, and Southeast Asia). For background information on HTFP data, please see the Tropical Rain Forest Information Center (TRFIC) at Michigan State University. The TRFIC is a NASA Earth Science Information Partner (ESIP).
The North American Landscape Characterization (NALC) project is a collaborative effort between the Environmental Protection Agency (EPA) and the U.S. Geological Survey (USGS) to provide complete coverage of the conterminous U.S. and Mexico for the purposes of mapping land cover and land cover change.
 NALC Triplicate Improvements Summary
The Global Land Cover Test Sites compile time-series data of Landsat (MSS and TM) and NOAA AVHRR for selected sites that have been the subject of long term research and monitoring.
