Automatic Match Between Delimitation Line and Real Terrain Based on Least-cost Path

Concerning that it mainly depends on manual adjusting to realize the match between delimi-tation line and real terrain,this paper proposes the general solution to automatically complete above-mentioned match based on Least-Cost Path Analysis,and studies its key technology.First,terrainfeatures network is built via reverse search based on dangling terrain features grid and processed underthe guidance of delimitation theory.Then,cost layer is constructed for Least-Cost Path Analysis inorder to carry out above automatic match.Finally,some experiments are conducted so as to analyzeand estimate automatic match,which validates that automatic match studied in the article is feasibleand reliable.Additionally,some suggestions are provided for delimitation.
