Hi! I've tested your patch on my maps and it works great :). Thanks a lot for fixing it. Best regards Michal Rogala 2014-03-25 12:49 GMT+01:00 Gerd Petermann <gpetermann_muenchen@hotmail.com>:
Hi Minko,
thanks for testing. I always noticed the gaps, but I assumed that the all these ways were too short to be rendered. I think for the default style this is still true for many of the gaps.

Subject: Re: [mkgmap-dev] dissapearing roads
Looks good Gerd, Havent noticed it before but there were quite a few roads with gaps on lower zoom levels and the gaps are gone now.
Hi all,
attached is a patch with a modified DouglasPeuckerFilter to solve the problem with "disappearing roads". I see only small differences in the maps, so I hope it doesn't introduce any side effects.
The problem occured when - due the rounding of coordinates to low resolutions - a line is converted to a straight line with a spike. This is not directly related to mergeLines, but is more likely to happen with it.
If I hear no complains I'll commit that patch on wednesday. Compiled binary based on trunk r3118: http://files.mkgmap.org.uk/download/191/mkgmap.jar
