Abstract
Development of satisfactory techniques for detecting change in coastal zone environments is required before operational monitoring procedures can be established. In an effort to meet this need a study was directed toward developing and evaluating different types of change detection techniques, based upon computer-aided analysis of Landsat multispectral scanner (MSS) data, to monitor these environments.
Four change detection techniques were designed and implemented for evaluation: a) post classification comparison change detection, b) delta data change detection, c) spectrali/temporal change classification, and d) layered spectral/temporal change classification.
The post classification comparison technique reliably identified areas of change and was used as the standard for qualitatively evaluating the other three techniques. The layered spectral/temporal change classification and the delta data change detection results generally agreed with the post classification comparison technique results; however, many small areas of change were not identified. Major discrepancies existed between the post classification comparison and spectral/temporal change detection results.
