[mkgmap-dev] [Patch] Improve Multipolygon handling

Hi, attached patch simplifies the code to join ways. The original code is slower (and in my eyes harder to understand) because it (sometimes) adds single points to the beginning of an ArrayList, which means System.arraycopy() for each insert. Esp. for level-2 boundaries, the ArrayLists can be > 100000 elements. http://gis.19327.n5.nabble.com/file/n5521191/MultiPolygonRelation.patch MultiPolygonRelation.patch Gerd -- View this message in context: http://gis.19327.n5.nabble.com/Patch-Improve-Multipolygon-handling-tp5521191...
