MapGIS多边形拓扑错误的处理及避免方法

MapGIS使用过程中经常会遇到多边形拓扑错误,错误处理步骤较为繁琐。针对这种情况,在分析了MapGIS中拓扑错误产生的原因,以及如何通过弧段转线处理法来解决这些拓扑错误,同时文章还延伸出了如何避免出现这些多边形拓扑错误。通过避免这些错误,不仅仅能减少工作量,提高工作效率,而且对于达到土地规划规范的要求具有重要作用。

Study on Conducting and Avoiding Polygon Topology Errors in Using MapGIS Software

During the period of using MapGIS software, polygon topology errors can often be met. Error processing steps are very complicated. In view of this kind of situation, on the basis of analyzing the reasons for causing these errors, how to conduct and avoid the polygon topology errors as well as the processing techniques are studied in this paper. Through avoiding these errors, woek amount can be reduced, work effect can be improved, and the demand of land plan can be reached as well.
