The applications developmental data system

This paper describes a research and development system under development at NASA Goddard Space Flight Center (GSFC) for processing Landsat-4 Thematic Mapper (TM) data at high throughput rates. This system, called the Applications Developmental Data System (ADDS) is being developed with 2 objectives. First, during the initial year of Landsat-4 operations, ADDS provides an essential link in processing the TM images for image data quality assessment. The second objective is to demonstrate the ability to produce a radiometrically corrected TM image in 8 minutes and a geometrically correct image in 16 minutes. The processing rates currently achieved are presented.
