基于XML的国土空间基础数据集成方法

Integration Method of Land Spatial Basic Data based on XML

为了提高国土空间基础数据集成效果,提出基于XML的国土空间基础数据集成方法。在国土空间基础信息平台的基础上,构建一套国土空间规划体系,划分国土空间的结构。通过设定国土空间的适应性条件,给出不同国土空间之间存在的相互作用关系,结合相对性权重检验,确定国土空间规划目标函数。引入XML解析方法对国土空间基础数据解析处理,通过计算国土空间基础数据集成的聚类距离,获取数据特征之间的相关性,实现国土空间基础数据集成。实验结果表明,文中方法可以加快数据集成速度,并提高国土空间的划分效率。

In order to improve the effect of land spatial basic data integration,an XML-based land spatial basic data integration method is proposed.On the basis of the basic information platform of land space,a set of land space planning system is constructed,and the structure of land space is divided.By setting the adaptability conditions of land space,the interaction relationship between different land spaces is given,and the objective function of land space planning is determined by combining the relativity weight test.The XML parsing method is introduced to analyze and process the land spatial basic data.By calculating the clustering distance of the land spatial basic data integration,the correlation between data features is obtained,and the land spatial basic data integration is realized.The experimental results show that the method in this paper can speed up the data integration and improve the efficiency of territorial space division.
