Hi Ticker, I think many limits in mkgmap are based on findings in Garmin maps existing before 2010. Feel free to play with them. I think I once tried 0xffff for these values and got problems, so I stopped investigating. You might be right that the value should depend on the resolution.

Won't this will cause unnecessary cutting at low res map levels?
