Water Quality Determinations in the Virgin Islands from ERTS-A Data.
Abstract
The harbor at Charlotte Amalie on St Thomas, Virgin Islands, has a concentration of many factors affecting water quality: Untreated sewage effluent; Sediment from navigation and dredging operations; Runoff from a garbage dump, and Hot effluent from a desalination/power plant. Imagery from ERTS-A in association with aircraft imagery and ground truthing permits the characterization of water quality in terms of absolute color values. This necessitates the establishment of photometric standards resolvable by the ERTS-A sensors in order that atmospheric effects, which generally vary on sequential overpasses, may be determined and subtracted. The overall program for doing this is described together with typical numerical results. (Author)
