[mkgmap-dev] [PATCH v1] Check size of polygons to avoid exceeding subdivision size

Wed Jun 22 18:57:17 BST 2011

Hi Nop,

please post your options file and your style file (if you don't use the 
mkgmap default style). Both have an influence on the map creation which 
also means that they influcence which data is used to build the 
subdivisions.

So you added some error messages to the code (Max region size exceeded, 
Area max dimension)? Please check if these are the only changes and post 
a patch with your error messages so that I can fully understand where 
the problem occurs.
