Integration of GPS, remote sensing, and GIS techniques for coastal resource management

Global Positioning System (GPS) surveys, photogrammetric aerotriangulation and compilation procedures, computer-aided image analyses, and conventional air photointerpretation techniques were employed to construct a geographic information system database for Sapelo Island and its bordering marshlands. This database includes 1:5000-scale topographic maps, 1:24,000-scale thematic maps, and digital elevation models in digital format, and covers a 40-year period from 1953 to 1993. It will facilitate the management of natural resources within the Sapelo Island National Estuarine Research Reserve (SINERR). Geographic information system overlay techniques indicate that Sapelo Island has increased in size by about 10 hectares (ha) per year between 1953 and 1974, and by one ha/yr from 1974 to present. While the areal extent of marshlands has remained relatively constant since 1953, logging on the island has increased significantly in recent years. The integrated approach employed in this study may be used to monitor coastal reserves throughout the United States. 10 refs.
