This study evaluated the utility of multispectral aerial video remote sensing data to map and monitor hazardous waste sites. The use of a video system offers several potential advantages over conventional photography for an operational monitoring program. These advantages include the immediate availability of multispectral data in either analog or digital form which can be acquired and stored efficiently and at low cost. Multitemporal comparison of airborne video data and conventional color infrared photography indicated that bi-spectral video data could be acquired and analyzed at sufficient resolution to accurately map a waste processing site near Phoenix, Arizona. Applying image processing and GIS techniques to the digitized video and photographic data permitted the effective generation of multitemporal land-cover maps that provided valuable information on the changing status of the site.
