Abstract  

3.Gansu Administration of Survey,Mapping and Geo-information,Lanzhou 730000,China)
Correcting RPC file come from WorldView-2 images on the basis of GPS ground control points,the Digital Elevation Model (DEM) in 1∶5 000 was rapidly extracted using the image matching technology of digital photogrammetry software system based on the three\|dimensional model in Dayekou watershed (DYK) in the upper stream of the Heihe river basin.Due to the complex terrain,inaccessible area,south of the study area hadnt ground control points covered.Based on the interactive operation of the three-dimensional model,60 tie points distributed uniformly were obtained to improve the accuracy of the automatic extraction of DEM.And in main areas,such as the shady forest coverage,the Dayekou reservoir and so on,we must edit the DEM by revising and adding the terrain feature points,and line data can improve the accuracy of the results.Check points were composed of 15 GPS points and 12 model confidential points,which used for quantitative validation.Results show that the maximum error was 1.9 m in the two sets,which achieve the requirements of one degree accuracy of 2.5 m in this mountain scale.

Key words:  WorldView-2      Dayekou watershed      Image matching      DEM
