摘要
[目的]为解决地籍数据建库过程中出现宗地要素重叠的问题,提高地籍空间数据的质量,保证数据的拓扑空间一致性,设计出一种提取重叠宗地要素的自动化检查工具.[方法]根据空间拓扑关系九交模型对要素间的重叠类型进行识别,在AutoCAD平台上借助AutoCAD.NET的布尔运算机制实现要素重叠的自动提取.[结果]自动化检查工具实现了地籍空间数据中各宗地要素之间的重叠检查,可直接对数据进行处理,生成定位重叠多变形的DWG文件.[结论]基于AutoCAD.NET开发的自动化检查工具能够准确地检查出存在重叠的多边形,避免了人工检查工作量大且容易出错的缺点,提高了地籍空间数据的质量和成图效率.
Abstract
[Purposes]This paper aims to solve the problem of overlapping land elements in the process of building cadastral data databases,improve the quality of cadastral spatial data,and ensure the topologi-cal spatial consistency of the data.[Methods]This paper identifies the overlap types between features based on the nine intersection model of spatial topological relationships and uses AutoCAD on the Auto-CAD platform NET's Boolean operation mechanism to achieve automatic extraction of element overlap.[Findings]The automated inspection tool has achieved overlap checking between various land elements in cadastral spatial data,which can directly process the data and generate DWG files with multiple defor-mations and positioning overlaps.[Conclusions]Based on AutoCAD The automated inspection tool devel-oped by NET can accurately detect overlapping polygons,avoiding the drawbacks of heavy workload and error-prone manual inspection,and improving the quality and mapping efficiency of cadastral spatial data.
