COASTAL WETLAND MAPPING

The U.S. Geological Survey is conducting a research project in the vicinity of Sapelo Island, Georgia, to investigate procedures for interpreting, delineating, and mapping coastal wetlands using remote sensing and photogrammetric techniques. The study area contains a variety of coastal marsh conditions, from saline to brackish, and extends from a mainland river through sea island marshes to the Atlantic Ocean. Orthophotoquads are prepared at 110,000 scale with a format of 2.5 minutes of latitude and 3.75 minutes of longitude. Coastal wetland boundaries and plant species associateions are interpreted and delineated on the orthophoto base. In addition, the boundaries will be digitized for computer analysis. The primary objective is to evaluate the accuracy, time, and cost for mapping coastal wetlands. The results of the investigation should be of value to Federal and State agencies with responsibilities for mapping or regulating the coastal zone. /Author/
