辦理中央管河川川秀姑巒溪計畫河段航拍作業，以航空測量專業技術建置計畫河段基本圖資，產製包括正射影像、數值地形圖、DEM及斷面圖等數值圖資資料，並整合蒐集及分析其他數值資料，以提供後續辦理秀姑巒溪水系治理規劃設計、流域經營管理及流域環境自然生態保育與環境營造之應用。

Taiwan located on the Circum-Pacific seismic zone in the West Pacific Ocean. The special geographical qualification caused frequent natural disasters such as earthquake and typhoon. Recent years, the global climate changed obviously, makes these phenomena occur much often than before. In the case of restraining the land development and decreasing the harm of natural disaster, a relevant project called “construction of the spatial information system of central government administered rivers” was activated in 2005, which was a part of National Land Restoration Strategic Program and Action Plan. One of the 8th-year goal focuses on the development of digital environment database for Xiuguluan River. In addition to new acquired aerial imagery, the existing digital archive would be also imported to central river 3D web geographic information system (GIS) for display and relevant application. Furthermore, the product such as the interpretation of river state and land-use map by aerial photos could supply the useful reference for the following applications like environmental protection, ecological preservation and river remediation. The area of interest includes the Xiuguluan River mainstream from Gauliao Bridge to boundary point and its branches, Gauliao River, Lehe River, Zhuo River, Lele River (including Qingshui River), Antong River, Amei River, Majialu River, Jiuan River, Luntian River (including Xiuluan River), Luozai River, Bie River and Dapo River. The products cover region amounted to 20,811 hectares of orthophotos, 6,088 hectares of digital elevation model (DEM) and 3,616 hectares of digital topographic maps. This plan collected the maps of environmental resources, including 7 types of classifications and 51 kinds of images, which would be imported to the 3D GIS (which was mentioned in the previous paragraph) as well. In addition to the prescribed works, we would supply 3D interactive GIS product as additional service. The advanced technique of virtual reality display is also an especial feature in this project.
