[mkgmap-dev] Wrong turn restriction warnings

From GerdP gpetermann_muenchen at hotmail.com on Fri Feb 21 19:57:17 GMT 2014

Hi Carlos,

you say that you see the message for the turn restriction in mkgmap.
If one of the ways of relation 1610018 crosses the tile border,
splitter will write all members of the relation to both tiles, but it 
is only usable in the tile that contains the via point.
