做任务时需要运用到局部莫兰指数,卡在用Python计算的思路上好久,最后发现可以用ArcGIS进行处理,步骤简单易懂。

主要步骤为:

1.读入数据(一定要为shp文件),对于用ecognition直接导出的shp文件可能不能直接计算,可以先将标签图读入,然后转换为shp文件,再对shp进行处理

2.运用ToolsBar中的空间管理工具---聚类分布制图---------聚类和异常值分析工具,进行局部莫兰指数的计算。(如果要计算全局莫兰指数,则为空间管理工具---分析模式---------空间自相关工具)

选择好参数,输入字段选择gridcode,点击确定进行输出。

关于莫兰指数的理解,可以看这个文章:https://blog.csdn.net/shine4869/article/details/106250354/
