[mkgmap-dev] dissapearing roads

Sun Mar 23 20:03:09 GMT 2014

Hi Michal,

You said that GPSMapEdit shows that the way is really missing. I saw lines
with
the types you use (0x1101b and 0x1101d), both with and without
--preserve-element-order.

My idea if mkgmap is not the problem: If two lines with identical points and 
types are rendered by Garmin tools, maybe they nullify each other. 
It is easy to detect that case in mkgmap, but probably CPU intensive.
