| 摘 要： | 基于ArcGIS Engine的核心组件功能实现了空间离散点生成等值线,并针对ArcGIS Engine在生成等值线分布区域方面的不足,提出采用等值线分割确定研究区域边界、构建等值线分布区域树的算法,实现了等值线分布区域、拓扑关系构建及高程值的计算,最终实现了分层设色图的自动生成。通过浙江省金华市地下水水位等值线与分层设色图的自动生成试验,表明该文的技术路线是可行的。

| Abstract: | Based on core components of ArcGIS Engine,the contour plotting of spatial scatter data is effectively achieved in this paper.In response to the limitation in generating the contour distributing region by ArcGIS Engine,the algorithm that contour cuts the boundary of research region and to build the contour distributing region tree is brought forward,which realizes generation of contour distributing region,topological relation,height value and hypsometric maps automatically.According to the trial for automated generation of ground water level contour and hypsometric maps of ground water in Jinhua City,Zhejiang Province,it proves that the technical way is available and can be provided with application value. |
