EVALUATION OF SATELLITE REMOTE SENSING AND AUTOMATIC DATA TECHNIQUES FOR CHARACTER-IZATION OF WETLANDS AND COASTAL MARSHLANDS

摘要

The evaluation was conducted in a humid swamp and marsh area of southern Louisiana. Earth Resources Technology Satellite (ERTS) digital multispectral scanner data is compared with similar data gathered by intermediate altitude aircraft. Automatic data pro¬cessing is applied to several data sets to produce simulated color infrared images, analysis of single bands, thematic maps, and surface classifications. These products were used to determine the effective¬ness of satellites to monitor accretion of land, locate aquatic plants determine water characteristics, and identify marsh and forest species The results show that to some extent all of these can be done with satellite data. It is most effective for monitoring accretion and least effective in locating aquatic plants.
