分析思路:一、传统处理办法:利用要素属性表关联,新数据ID连接旧数据ID,比较新旧XY是否一致,添加字段用来记录新旧XY的比较结果,筛选出不一致的记录。 1.新旧表连接字段,用Join Field (Data Management),工具箱中--数据管理工具--连接--连接字段 2.对连接后的表添加字段,用Add Field (Data Management),工具箱中--...

arcpy.AlterField_management(os.path.join(workspace, feature_class), old_field, expression) ``` 在上述代码中,我们首先导入了`arcpy` 模块。然后,我们设置了工作空间和要素类的路径。接下来,我们定义了要修改的字段(`old_field`)和新字段的名称(`new_field`),以及新字段的类型(`field_type`)和长度(`field...
