Abstract:

Fildes Peninsula is one of the most significant regions for polar scientific research. The high resolution digital orthoimage map(DOM) of this region provides important information. However, influenced by the quality of ground control points(GCPs) and DEM , the existed DOMs are inadequately precised for high accuracy application. Regarding this, this paper addresses DOM generation based on QuickBird images of Fildes Peninsula. Combined with the GCPs collected during CHINARE-25 and the DEM created from the 1:20000 topographic map, the ortho rectification model and height displacement are meliorated. The result shows that the plane error of the image is less than 1 meter, which can meet the requirements of 1:5000 remote sensing cartographic map.
