摘要
为了提高不动产数据编辑的效率,笔者研究了QGIS软件中图形编辑时出现的几种不易处理情况,比如面与面相交细小、拓扑错误以及多部分实体等情况。利用QGIS支持插件的特点,通过Python语言开发了图形编辑插件,利用QGIS软件中图形ID号唯一的特点,实现了QGIS与AutoCAD之间的数据转换,从而解决此类问题。
In order to improve the efficiency of real estate data editing,the author studies several difficult situations when graphics editing in QGIS software,such as the small intersection between face and face,topological errors and multi-part entities.Based on the characteristics of QGIS support plug-in,a graphics editing plug-in is developed by Python language.The data conversion between QGIS and AutoCAD is realized by using the unique characteristics of the graphics ID number in QGIS software,thus solving such problems.
