Spatial buffer analysis

In this paper we use two important methods of the spatial analysis, the buffer analysis and the overlay analysis. We get the correct area by adding the resident data to the road data.

方法中主要运用了缓冲区分析和叠置分析，通过把居民地层数据叠置到道路层数据进行联合分析，为道路网的自动选取构建出了正确的空间拓扑关系。

In normal application of a GIS buffer zone analysis, we always need to pick an object in that specific spatial area.
