[mkgmap-dev] Smaller Tiles?

Wed Sep 9 13:04:55 BST 2009

I've just updated to the latest mkgmap from trunk and am now having
problems processing tiles that I have previously successfully processed.
The error I am receiving is

java.lang.IllegalStateException: Polygon offset too large

This is when run against a tile containing only contours. If I
regenerate the contours using maxnodes=50000 (rather than the default)
then mkgmap finishes but I would prefer to keep them larger if possible
and this is obviously changed behaviour if I have previously been able
to compile against these tiles. I would say this starting happening
within the last 10 commits but can't say exactly when
