由於近年來，全球氣候變化日益顯著，造成台灣遭受天然災害之機率增加。尤其在由於近年來，全球氣候變化日益顯著，造成台灣遭受天然災害之機率增加。尤其在98年8月莫拉克颱風侵台（八八水災），所挾帶之超大豪雨重創台灣中南部；其中高屏溪本流、口隘溪及濁口溪受災嚴重，目前高屏溪本流、口隘溪及濁口溪復建已完成，為瞭解莫拉克颱風災後復建防洪設施重建現況、河川治理規劃（檢討）及河川管理需要，爰此辦理「高屏溪本流及支流數值地形及圖資建置計畫」，計畫以航拍技術產製正射影像圖、數值地形圖及數值高程模型(DEM)等數值圖資，以利充分了解災後復建防洪設施重建現況，以做為後續辦理河川治理規劃(檢討)工作及河川管理之需要。 本計畫除配合航拍產製計畫各河段正射影像數值圖資外，並針對航拍範圍製作數值地形圖及數值高程模型(DEM)等資料。提供後續辦理水系治理規劃檢討及流域環境自然生態保育與環境營造應用。並將完成之各項數值圖資成果納入經濟部水利署「中央管河川三維網際網路地理資訊系統」及「地理資訊倉儲中心」，作為業務查詢展示應用。

Due to the increasingly apparent global-climate changes in recent years, the probability of natural disasters in Taiwan occurs. Especially the Typhoon Morakot in August 2009, which caused heavy damages in central and southern Taiwan by cloudburst. Among them, the Gaoping River, Kouai River, and Zhuokou River have been reconstructed. In order to realize the flood protection facilities rebuilding situation and the rivers management planning after Typhoon Morakot, the plan “Digital Elevation Model and Map Information Establishment of Mainstream and Tributary of Gaoping River” has been set up. For the purpose of fully understand the flood protection facilities rebuilding situation after disaster, the aerial-photogrammetry for the orthophoto, digital surface model and digital elevation model are conducted, and the final result can be used as the rivers management planning in the future as well. The area of digital elevation model and map information establishment includes the mainstream of Gaoping River (Railway bridge over the river to the sea), the areas mentioned above will be measured at the same time (the horizontal datum is TWD97【2010】 and the vertical datum is TWVD2001). The jobs entrusted include aerial-control points emplacement, announced control points examination, horizontal control measurement, and vertical control measurement. For the purpose to detect the change of the plan area, we collecting DEM and ortho images to do chang detection. The results of chang dectection will be the base data for the river harnessing.
