I was just talking to Jesse about this yesterday. Such a functionality is definitely needed and now, thanks to the work on the table, starts to be possible. It will require (1) being able to load tables from text file, say as Comma Separated Values, and (2) being able to join based on a key, which will have to be unique in the text file Note also that the general solution would require being able to create new columns in the shapefile attribute table to serve as the key. This is needed because it's not guaranteed that the user can calculate from scratch the values in one of the geometric columns to use that as a join: consider a shapefile of states without any attributes where the user would have no way to create a join column in their CSV file. So we have a little bit of work to go on this feature request... cheers, adrian > > On 30-Nov-06, at 7:22 AM, John Oeffinger wrote: > > > I'm a newbie to both GIS and uDIG so please excuse this very basic > > question. > > > > I have gone through the walkthroughs, watched the Flash tutorial, > > and checked the help area. > > > > Can a user add text delimited data to a map? > > > > Can someone point me to information on what needs to be included in > > a data file to be added to a map? > > > > All I need to do is add election return data or some non-census > > state statistical information.
