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。
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.
