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

• 摘要: 针对当前划界工作中主要采用手工操作实现划界线与实际地形匹配的现状,提出了基于成本最优路径分析实现自动匹配的基本原理,研究了自动匹配的关键技术。首先,基于悬挂特征栅格的反向追踪构造地形特征网络,并借助划界法理对其进行特殊处理。其次,构建成本图层,应用成本最优路径分析实现了划界线与实际地形的自动匹配。最后,通过实验对匹配结果的可靠性进行评价,验证了本文自动匹配方法的有效性和可靠性,并对划界工作提出了若干建议。

Abstract: 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.
