[mkgmap-dev] Subdivision width is 36627 at 3230916/1236133

Sat Apr 28 12:15:36 BST 2012

Hi Marko,

well, I know now what element is causing the problem. It is the way

http://www.openstreetmap.org/browse/way/127417755

maps created with r2272 will not show this way if the resolution is high
because it is very long 
and consists of only 11 points, and some of them are very far away from each
other.

I am now working on a patch which 
a) allows to detect this situation and
b) calculates intermediate points
