For planning and operation of shore protection facilities against beach erosion, it is necessary to understand the shoreline change trends.
Conventionally, aerial photographs are used for detection of shoreline changes. However, the major drawback of the aerial photograph is its prohibitive high cost in terms of data acquisition and processing time.
In this study, a shoreline change analysis system using satellite images from ALOS (Advanced Land Observing Satellite) has been developed. In this system, the location of shoreline is extracted as vector data from the ALOS images and previous aerial photographs.
Finally, comparison of shorelines in the vector data is carried out automatically using a GIS (Geographical Information System) system.
