查询词典 polygon

The paper use the GIS methods to creating the basic spatial information database, and processing the polygon data by overlapping analyst, the linear data by network analysis, the statistic data by join analysis, the evaluate data by superaddition analysis, and these methods make the data collection, organization and analyst more easier, and the thematic map make the result more intuitionistic. Especially, through combined the graphics processing and the spatial data operation organically, the spatial overlapping analyst resolved the division from natural elements to administrative evaluate units.

应用GIS技术建立空间基础信息数据库，进行面状要素叠加分析、线状要素网络分析、统计要素链接分析和赋值要素追加分析，使分区数据的采集、组织和分析更加简单；专题地图的应用，也使分区方案的表现更为直观；尤其是GIS空间叠加分析功能通过图形处理与空间数据运算有机地结合，解决了自然分区和行政分区界限中的若干要素的切分问题。
