Concern for the coastal zone throughout the United States has prompted implementation of geographic information systems GIS that can store the vast amounts of information on the infrastructure of these delicate environments, access and use the stored data to analyze changes that are occurring, and portray the results of analyses in the form of tables andor maps and map overlays. A specific GIS of interest to the US Army Engineer Waterways Experiment Station has been one that can be used to analyze land-loss conditions within the deltaic environments of Southern Louisiana. This GIS will allow Zenith, Model 248, or equivalent, microcomputers to be used to portray depletion in terms of the time period over which it has been occurring, where it has occurred, and the rate at which it is, or has been, occurring. This paper discusses some of the basic decisions that were made prior to implementing the GIS, the structure of the GIS, and some capabilities provided by the GIS using the stored data.
