In Taiwan, there are many abandoned mines located in both urban and rural areas. Most of them were not reclaimed. Since the problems of management and environment in such area should be concerned. In order to provide an efficient way to deal with such problems, we integrate the 3S (GIS-GPS-RS) technologies through the platform PDA and make it friendly operated. The geo-spatial data such as stopes of extracted mine, locations of adits (or shafts) as well as wasted dumps can be uploaded into database and provide optimal decisions for the government.
