How to clear attribute columns from a Shapefile?

Question

I want to clear all columns from a SHP. Only need geometry of features. I use QGIS and Sextante with grass and saga. Is there any tool for this job...

Answer 1

There are several tools you can use to Drop\delete columns.

1 - Atribute table "delete column" tool

• Open layer's attribute table;
• Start editing;
• Click on "delete columns" icon;
• Select several columns using Pressing Ctrl;
• Click ok;
• Stop\Save editing;

2 - Use Table Manager Plugin

• Install Table Manager Plugin using Plugins > fetch python plugins;
• Click on the plugin Icon or in Vector > Table manager > Table manager;
• Select several columns\fields using Pressing Ctrl;
• click on delete;
• Ok

Answer 2

A simple way of getting rid of the attributes is to rightclick on the layer -> Save As... and check Surpress attribute creation.

If you have many files, you could use:

ogr2ogr -select field_list destination_file source_file

to select fields you want (default is all!)
