The three image data sets were collected over Redfish Bay, Texas on the same day, under almost identical environmental conditions. Next, the data sets were compared to each another using a variety of criteria. Finally, automated methods were used to create maps of propeller scars and the accuracy of each map was analyzed. Significant findings include: 1- Digital airborne ADS40-52, DMC, and Ultra-Cam imagery can be used to effectively map benthic habitat and propeller scars. 2- Imagery from the DMC and ADS40-52 had the highest spatial accuracy. 3- Spectral separatability of benthic habitat class and propeller scars is best in the DMC and the ADS40-52 imagery. 4- The accuracy of propeller scar maps was highest for maps produced from the ADS40-52 data.
