Well, I've broke this cascaded relation into a simple one multipolygon relation, and mkgmap still doesn't draw a lake in a middle of swamp.
Hi!
Have you tried zooming out or/and reducing detail on the device, in Mapsource or Qlandkarte?
I observed that some (many) multipolygon holes only become visible when the low-detail version of the outer polygon is displayed...
Example: this farmland near the stream "Logebach" I mapped last Weekend: http://informationfreeway.org/?lat=50.663655772998936&lon=7.287712349115571&...
I had a second look at the multipolygons where this problem exists and found out that if I zoom in (on the device) with the cursor right on the edge of the multipolygon hole, I can select 2 "wood" polygons when the hole disappears. So i suspect that in high zoom levels, mkgmap cuts the holes correctly, but fills them with a polygon that has the same object type as the outer polygon. In my examples, this creates wood-in-wood polygons. Even though I can't code, I hope this helps to fix the problem... :-) -Martin
