Abstract : A preliminary algorithm has been developed for the extraction of water depths from Thematic Mapper (TM) scanner data. Algorithm development was based on 1978 aircraft scanner (ERIM M-8) data processed to simulate TM data, and on data available from the 1980 Photobathymetric Calibration Survey. The Defense Mapping Agency (DMA) constructed a series of overlays to the ERIM data set showing locations of ship soundings. These overlays were used as a basis to extract corresponding TM simulated signals from the aircraft data set. Water depth prediction algorithms were developed based upon relationships between the simulated TM data and the measured water depths. Results will aid the development of bathymetric processing procedures for Thematic Mapper data. (Author)
