Arcgis操作: 批量修改属性表
2022-07-07 07:15:00 【稻田里展望者】
在通过arcgis进行数据处理时, 有时需要对一个图层的属性表中一个字段的进行批量的重复修改,这时简单的打开编辑器对属性表进行单独的编辑修改已无法满足海量数据的需求, 这时需要通过批量处理的方法进行字段属性的修改
使用工具: 按属性选择工具 和 字段计算器
基本思路: 通过属性选择来根据条件把需要修改的数据筛选出来,然后通过字段计算器把已选的数据进行修改
案例: 把属性表中name字段为空的数据填上’没有数据’的字段
打开属性表, 如下:
通过按属性选择工具把空白的数据选出来


通过字段计算器把已选的数据进行修改,把数据批量改成"没有数据"
选中整列字段
右击选中字段计算器
打开字段计数器,输入没有数据(字符串要加上双引号)
点击确定,查看结果,选中的数据已被批量修改了
