[Gvsig_english] how to modify attribute table

[Juan Lucas Dominguez Rubio]

Hello,
 
I think it is better to use the JOIN option. If you fill in the vote cells of the attached file VOTE.DBF, you will be a dozen clicks away from your map:

DIST_ID is the identifier of each district. You can open the DBF file with Open Office as a spreadsheet then save it as a DBF again.
 
I used this shapefile:

Asunto: [Gvsig_english] how to modify attribute table



I'm a novice GIS user. I am trying to modify the attribute table of a .shp file of the U.S. Congressional Districts so that I can show "yea" and "nay" votes on a particular bill. I am assuming there is a way to add a column to the attribute table where I could put in the vote. Then I am supposing I can assign colors to the districts based on the way they voted. Can anyone help me do this? Here is the link to the 110th Congressional Districts shapefile: http://nationalatlas.gov/atlasftp.html#cgd110p.

 

If anyone can help I would be very grateful!
