Coastline Accuracy Assessment Developed By Using Multi Data Source

Coastline Modeling Accuracy Assessment Developed By Using from Multi-Source Data. The coastal regions need to be developed because many big cities in Indonesia are located these areas. However, it is crucial determine the distance beach that safe as requirement for development along zone. term of very closely affiliated with coastline. method determining coastline continues fulfill needs related has a dynamic position. land contour coast and tide's state become several things affect Therefore, model required define positioning both conditions easy change. determination multi-source data modeling using DEM results rarely done. In this study, uses height contours combined sea depth Mean Sea Level (MSL) value vertical reference model. model's accuracy tested by comparing delineation Geospatial Information Agency test generated before reference. Based on compared shoreline models have gaps. This gap might influenced source, resolution, collection method.
