摘要:In 1990, a portion the Atlantic Ocean beach of Hilton Head Island was renourished using sand takenfrom nearshore borrow sites. The Town's Geographic Information Systems (GIS) staff has been studying theeffects of the renourishment project on offshore areas through the use of satellite images and data. The studyconsisted of acquiring SPOT images and historical photography of the Hilton Head area from various timesbefore and after the renourishment project. The images were processed and specific features converted to GIScoverages for analysis. Bathymetric data from nautical charts was updated using bathymetry derived from thesatellite data. Results of the study consist of data showing the geometry and motion of shoals both before andafter the renourishment. In addition, the configuration and extent of a large area of underwater 'sand waves' ,located from the shore to 5 kilometers offshore, were described and monitored. The full extent andconfiguration of this area were previously unknown. The use of the satellite derived data in various computermodels is also discussed. This study revealed several points in the process of coastal planning where satellitederived data could be profitably used, such as borrow site selection and ongoing monitoring
