| 摘 要： | 讨论了传统的矢量叠置分析在初始化、数据冗余、误差等方面存在的问题,而基于栅格模式的叠置分析则可以消除这些问题,在此基础上给出了多重多边形叠置栅格算法,运用此算法进行了湖北省城镇化水平的实证分析。

| Abstract: | Some problems such as initialization,error and data redundance of overlay based on vector way are discussed.All of the problems can all be well solved by grid way.A new way of overlay analysis is presented,and proved reasonably by the case of analysis of the town level in Hubei province. |
