一种基于节点共面的VCT 3.0面间接线构建算法

An Algorithm for Constructing Indirect Lines of Face on VCT3.0 Based on Area Feature Node Sharing

VCT文件格式是一种广泛使用的数据交换格式国家标准,并且三调成果中矢量数据最终会以VCT格式进行汇交。本文提出一种面要素的间接线构建算法,实现了将面要素的矢量信息精确地转化为符合VCT3.0标准的间接线数据。算法通过KingMap V6.0平台实现并在实际数据中进行测试,验证了算法的可行性和正确性。

VCT file format is a widely used national standard data exchange format,and vector data in the third national land survey results will eventually be intersected in VCT format.In this paper,an algorithm is proposed for constructing indirect lines of area feature,which can accurately convert the vector information of area feature into indirect line data in accordance to VCT3.0 standard.The algorithm was implemented on KingMap V6.0 platform and tested in actual data,which verified the feasibility and correctness of the algorithm.
