Hi I'm getting inconsistent displays in, for example, an area with woods and a large sports area, also area of wetland with many lakes (not expressed as outer/inner relation).
From my reading of the code, the problem occurs where the larger polygon crosses a subdivision boundary. It seems that its full area is allocated to just 1 subdivision, even though it might span many.
In the subdivision to which the large area is allocated, it is drawn first, then the small areas are drawn, overwriting nicely (because the shapes in the subdivision have been sorted by decreasing size). But in an adjacent subdivision the small areas are overwritten. Shouldn't polygons be split on subdivision boundaries? I can't see any code that does this. Regards Ticker Berkin
