In that run, I had split finland.osm.bz2 into three tiles, at two latitudes: lat=62.578125 and lat=64.819336. Later, to get rid of a data structure overflow in the southern tile, I moved the southern boundary to lat=62.226562. You can get my files at http://www.polkupyoraily.net/osm/. > The splitter puts only parts of the ways that crosses the tile bounds to > the resulting tile file.

The lake runs from lat=64.6895 to lat=64.8580, crossing my northern tile boundary of lat=64.819336. > By the way: did you see that lake with the old mp code and the same > splitter bounds? There are many missing lakes in Northern Finland, even large reservoirs that are shown on Garmin's base map. I have not paid much attention to lakes before. Many lakes are displayed just as coastlines, but I hope that I can soon enable sea polygons. Finland's thousands of lakes and islands should be the ultimate "acid test" for multipolygon handling.
