ABSTRACT
Extensive use of Landsat data for monitoring and managing various resources, along with detailed field and laboratory studies, have pointed out the need for Earth observation sensors of improved performance. Users are demanding data with better spatial, spectral, radiometric, and temporal resolution. Improvements in the quality of data products also are required, especially in the area of geometric (location/internal distortions) and radiometric accuracy (absolute/relative). For many applications like disaster monitoring/mitigation and agriculture, quick delivery of data is demanded.
