An automatic method for contour matching inspection

The DEM data contour matching inspection is a common method of the DEM inspection, According to the contour matching inspection is still mainly through manual inspection, labor intensity, work efficiency is not high, In this paper, a method of automatic contour matching inspection is proposed, This method process the DEM data by calling a plurality of GP(Geoprocessing) tools according to a certain procedure, The proposed algorithm which remove misinformed result is used to process the data, Finally, all the problems in the DEM data can be located. Through the experiments, and the experiment results analyzed, this method can quickly locate the difference, and improve the efficiency of manual inspection.
