摘要
为了快速进行空间数据的分类,引入决策树方法,提出空间决策树思想.将空间数据中的空间属性作为测试属性,计算相关信息熵,从而构建所需要的决策树.以奥运会临时超市网点设计为例,用空间决策树法构建不同商区的人流树状图,得到了较清晰的人流趋向树状图.
In order to quick classify spatial data,the method of decision tree is introduced, and the spatial decision tree thought is put forward. The space attribute of space data is treated as the test attribute to calculates the relevant information entropy, then to construct the needed decision tree. Taking the nation- al olympic sports center as an example, people tree in different business space is construct by using deci sion tree method,and a clear tendency of people tree is obtained.
