A geological Geographic Information System (GGIS) for the basins of rivers administered by the Water Resource Agency was established and periodically updated in the previous (2004-2013) projects. During 2004-2013, field verification was carried out in 24 river basins (including the Lanyang, Fongshan, Touchien, Jhonggan, Houlong, Da-an, Dajia, Wu, Jhuoshuei, Beigang, Puzi, Bazhang, Jishui,Zengwun, Yanshui, Erren, Agongdian, Gaoping, Donggang, Hualien,DanShui, and Huang River basins) to confirm and to establish the data sets of geo-hazard, geologic outcrop, aerial-photo interpretation, and geologic interpretation of these basins in the GGIS. The objectives of the 2014 project covered (1) the collection of new data, (2) the field verification of the Xiuguluan and Heping basins, (3) the maintenance of GGIS and its user interfaces, (4) the implementation of Web-GIS and (5) training courses. The total numbers of verification sites of the basin verified in Xiuguluan and Heping River basins are 169, which include 34 rock outcrops and geologic structures, 91 sites of riverbed conditions, 24 of geo-hazards, and 20 sites of geologic interpretation. The verification results were compiled and built into the GGIS system.
