I am looking for tools for regionalization / districting in GIS.
So far I have been able to identify
- Districting ArcGIS extension (now also online)
- REDCAP (currently limited to 50k input polygons)
- iRedistrict (not yet released)
- R method
Is there anything else available out there? Especially something that will have no problems in dealing with quite large dataset [~ 1.3 million polygons]?
