Abstract: Data associated with mapping shoreline position provides baseline information used by scientists, managers, and planners for quantitative assessment of historical trends and prediction of future conditions. Unfortunately, many decisions based on application of this information rely on the assumption that all data and techniques are error-free. This paper provides an overall perspective of shoreline change assessment in light of potential errors associated with shoreline mapping. Proposed measurement and accuracy standards are presented within the framework of an automated process for organizing and integrating geographic information. A shoreline change GIS strategy is discussed, and application of this procedure for Harrison County, Mississippi is presented. This integrated design provides an accurate and comprehensive method for collecting, storing, retrieving, transforming, and displaying spatial data. Development of a national shoreline change data base for science and coastal zone management applications should proceed using this technology.
