A combined low cost airborne multispectral remote sensing system is described and evaluated for environmental resource management. The system consists of (1) Two 35 mm motor driven reconnaissance cameras using color and color infrared film. (2) Three optically filtered (including removable internal IR cut off filters), electronically shuttered CCD video cameras (Sony XC75) integrated into an airborne direct digital recording system using an 80486 processor, a 32 bit RGB video digitizing card and rewritable optical disk storage. (3) Two CCD based imaging spectrometers (VIFIS) providing approximately 10 mn bandwidth spectral data across the CCD spectrum (400 nm to 1,000 mn). These CCD video cameras were used with a variable interference filter fixed in front of the sensor surface. This provided a {open_quotes}rainbow{close_quotes} image of the ground varying across the imaged from 400 mn to 700 mn (visible) and 700 nm to 1,000 nm for the near infrared version. Field studies were undertaken to evaluate the performance of digital multispectral (DMV) imagery, supplementary reconnaissance photography (SRP) and VIFIS imaging spectrometry for mapping shallow water bathometry. The results indicate good performance in shallow water and suggest that with further refinement the system could be used over a broad range of resource management applications. 6 refs., 6 figs.
