I have two shapefiles.
I need to simplify them to display in a web page. The problem is that when I simplify them there are small discrepancies between edges on the regions compared with the same edges in the constituencies.
Is there any known tool or technique I could use to allow me to do the following:
- Simplify the regions shapefile and the constituencies shapefiles
- Ensure all edges which are common to both are the exact same
- Export a simplified regions shapefile and simplified constituencies shapefile
Up until now I've been trying it with Mapshaper.org and experimented with the different simplification algorithms and ratios. But I've not found a way to make it sync common edges between both. I'm aware of QGIS and ArcGIS, but have no idea if this kind of thing would be possible in them.
