Does anyone have a reliable dissolve tool that they would share. I have many cases where I need to dissolve parcels on a parcel_id (maybe up to 200,000 polygons in the whole file); I know I can bring it down into ESRI, but it adds multiple steps to my process. I'd like to have a Perl/python script that does: dissolve.pl parcels parcel_id The output being a shapefile named parcels_dissolve.* Where the inputs: parcels is a shapefile and parcel_id an attribute in the .dbf; The .shp, .dbf etc would be processed appropriately dissolving on the attribute passed in, so it could be parcel_id to dissolve parcels with similar parcel_id, or could be an attribute like zoning; the resulting output file would contain only one record in the .dbf file for each unique attribute. Additionally the only attribute left in the .dbf would be the attribute being dissolved on (unless you have the ability to sum area or count # of occurrences; but no other logic about which fields to bring forth; just the one attribute). Thanks for the help. I'd be willing to pay for this project to be written if someone is interested - drop me an email off list.
