We should probably join lines (like --merge-lines) and then prevent subdivisions from growing too much. The problem is that we grow subdivisions to fit lines so that there is a lot of overlap. The alternative is to limit subdivisions so that they only overlap a little and trim lines at their borders. It is similar to the same problem with splitter. Its hard to explain without a diagram, and I would like a tool that shows the layout of the subdivisions so that I can compare the strategy that we use compared to other maps.
I've just coded a small routine to draw a bbox gpx for each sub div. There seems to be one big difference: The sub divisions in the garmin map (extracted from gmapbmap.img) do not overlap, they are not even close together. Don't know it that is telling much, I think the img file contains only "Worldwide autoroute", no small streets.
