Hi, In the area I am working on, there is one block which I assume is the background color, that different from the surrounding area. Does anyone have any idea why? http://www.openstreetmap.org/?lat=-38.242&lon=144.398&zoom=11&layers=0B00FTF also http://www.openstreetmap.org/?lat=-35.9909&lon=150.1028&zoom=12&layers=0B00FTF Ian
