Hi at this point http://www.openstreetmap.org/?lat=51.984413&lon=5.216773&zoom=18&layers=M, the water in the north west corner looks to stream (pointers) into the south east direction, but the simple waterway on the right corner has the same pointers in the opposite direction into the north west. I cant find the meaning of the pointers in the advanced menu. Whats the meaning of them ? And where do they came from ? There seems to be no logic in them since I found them on borders alongside a canal pointing in opposite directions ? Greetz
