[mkgmap-dev] Bogus roundabout warnings

From Gerd Petermann gpetermann_muenchen at hotmail.com on Mon Mar 17 14:56:53 GMT 2014

Hi Marko,

if you are talking about the messages from ShapeMergeFilter:
A possible reason is a self intersecting polygon. The filter
assumes that shapes are not self intersecting, but
it doesn't test this yet. 
I'll have a look at them tomorrow.
