I have a shapefile with UK districts and unitary authorities. In the past, using commuting patterns, I worked out a new geography which is close to travel to work areas.
I now would like to create a new shapefile where UK districts and Unitary authorities are merged to create my new map of travel to work areas. I know it is possible to merge features manually by clicking the "merge selected features" icon. Only it is taking me ages...
Is there a way of programming this?
Is there a way to write some syntax in order to merge features?
That would help a lot, because I will be able to write the program and while I am running it doing something else. Also I would have the syntax saved somewhere.
I am using QGIS version 1.8.0.
