Re: [mkgmap-dev] Simplifying ways & rounding

Hello again,

Been trying your patch and it works well. Certainly doesn't seem to break the routing. However, it doesn't always merge ways that, as far as I can tell, should be merged. I have studied your code so I know how you're doing the matching. One thought, would rounding the coords before merging help? If it isn't that, something else must be not quite right.

I'm being so stupid today, it's the subdivisions. The lines that are not matching are in different subdivision so they don't get compared. That's a shame but the upside of only merging within a subdivision is that it's really quick. Mark
