Is there a good way to do map regions?
I'm making SVG game maps where a region on the map is a closed path. These regions usually share boundaries with one another so they often form a 'mesh' (consider a grid of squares or hexagons as examples, although for the maps the regions are rarely regular). To create them I have to copy and paste bits of path so that regions have nicely overlapping boundaries which works but is very tedious, particularly as I'd like to start building maps with large numbers of regions (>500).
I'm thinking I'd like to be able to start with a closed path (e.g. a continental outline) and treat it as a 'region mesh' - this would be like a normal closed path except that I could add a 'branch' node to it that would connect to another 'branch' node, creating two regions - these would be maintained as separate closed paths for export and the shared boundaries would always exactly overlap.
However, it seems likely someone has faced this problem before - there are lots of SVG maps out there that have regions defined in this manner. Can anyone point me towards a good solution for rapidly building a layer of map regions?

I don't really have an answer to your question, but while waiting for one you might want to look at
http://dev.w3.org/SVG/modules/vectoreffects/master/SVGVectorEffectsPrimer.ht... ('Using vector effects to produce shared borders on paths' at the end)
and at

My impression is that what you (and I) want is thought to be desirable but isn't available yet.

If you use Geospatial (GIS) software this is called topology. You can use QGIS, GRASS or a other GIS tools to draw your regions, then export the results to svg where you can pretty it up all you want.
Enjoy, Alex
