【摘要】 主要对在ＭＡＰＩＮＦＯ平台上如何实现管网空间位置分析、拓扑分析、缓冲区分析以及最短路径及事故分析等空间分析功能的实现思路和算法进行较详细的研究，并用实际探测的管线数据进行功能模拟。模拟后得到了较好的效果。更多还原

【Abstract】 The spatial analysis functions is the main function in GIS. and it is the main way to mine data. In this paper, the developing methods and algorithms about spatial location analyzing topological ana- lyzing, buffer analyzing, the shortest path analyzing and accident analyzing are studied based on MapInfo in detail. Meanwhile, these analysis functions are simulated by the field probing data, and the simulated result is satisfactory.更多还原
