| Aug 12, 2012 at 18:56 | comment | added | astaines | Very simply I want to agglomerate small areas with tiny populations to their neighbours, reasonably intelligently, to make up bigger areas with larger populations. As far as possible I want to leave areas with big populations alone. I can presumably specify this as some kind of optimization problem, but I don't know how to manage the spatial relationships.This is the key problem. If I could generate a list of areas to be joined up I'd be almost sorted, but I can't (except manually!) | |
