GIS空间数据拓扑运算在房产测绘中的应用及实现

Application and Implementation of GIS Spatial Data Topological Operation in Real Estate Surveying and Mapping

摘要:

房屋外半墙面积是房屋分摊面积的重要组成部分，其精度高低直接影响房产测绘成果数据的实用性。该文以自主开发的房产测绘软件平台作为依托，依据GIS空间数据拓扑运算对房产测绘中的相关数据进行处理，设计出一种仅由矢量数据参与空间数据拓扑运算的技术路线，巧妙地规避了房屋外半墙面积计算中的一般性及特殊性问题，提高了工作效率，节省了作业时间，更重要的是提高了面积测算精度，取得了良好的运算效果。

Abstract:

The exterior wall area of the house is an important part of the housing allocation area. Its accuracy will directly affect the practicality in real estate surveying and mapping. In this paper, based on the independent development of real estate mapping software platform, by using GIS spatial data topological operations, relative datas in real estate mapping have been condtucted, and a technology route which spacial data processing can be realized by only using vector data has been designed. It can avoid general and special problems in calculating exterior wall area, improve the work efficiency, save the operation time, and improve the accuracy of area measurement. It has achieved good results.
