The EDC DAAC was established as part of NASA's Earth Observing System (EOS) Data and Information System (EOSDIS) initiative to process,archive, and distribute land-related data collected by EOS sensors, thereby promoting the inter-disciplinary study and understanding of the integrated Earth system. The EDC DAAC role subsequently was expanded to include processing and distribution responsibilities related to Landsat 7 data. We archive and distribute ASTER and MODIS data from Terra , the first EOS satellite, and will receive MODIS data from Aqua. We also produce ASTER higher-level products. The archives at EDC hold the world's largest collection of civilian remotely sensed data covering the Earth's land masses. EarthSat TM Data Now Available! MODIS V003 Data Now Available!
