Re: [UMN_MAPSERVER-USERS] Merging Regions of a shapefile

[Brock Anderson]

Neil,

I tend to use Postgres/PostGIS for this kind of processing.
For example:

Load the data into postgres like this:

   shp2pgsql <loader options here> england.shp england_table | psql

Then dump it out again into several shapefiles. Use an SQL statement to 
select the regions to include in each file:

   pgsql2shp <dumper options here> england_table "select * where ..."
   pgsql2shp <dumper options here> england_table "select * where ..."
   pgsql2shp <dumper options here> england_table "select * where ..."

Hi Folks,

I've got a map of England as a shapefile, containing regions for each
county. What I'd like to do is merge selected regions in to a larger
region (E.g Devon, Somerset, Cornwall etc into "Westcountry").

Does any one know a simple (Preferably GUI based) way of achieving this?

Thanks in advance,

Neil.
