gis - Remove records from a shapefile

Question

I have a complete shapefile, but I just need 30% of the .dbf records. I clean the .dbf easily in SQL, but the connection with the shapefile is lost.

So, how can clean the entire shapefile of the records I don't need?

Thanks!

Answer 1

好的，我找到了解决方案。

1）进行查询删除不需要的元素：右键单击（RC）图层>属性>定义查询>查询生成器> ...>确定

2) RC on Layer > Open Attribute Table > table Options Button > Select All Records > Close the Table

3) RC on Layer > Data > Export Data > Select target folder > Save as type "Shape file" in the scroll-down menu

4) 将询问您是否要将新形状文件添加为当前项目中的图层 Y/N

5) 完成！
