Okay, it seems I have to look more closely to this. I did not understand that our quadtree allows to save areas (shapes). Or did I get this wrong? Splitting into subareas seems also to be a good option. > > You might also remove the merge step. For most tiles more than one > precompiled file is loaded. The bounds are merged afterwards.
