The result ended up looking like this: http://www.foseid.no/gustav/gallery/main.php?g2_itemId=1073&g2_imageViewsIndex=1 Compare with how this looks in OpenStreetMap today and in OpenAerialMap (iCube Landsat): http://www.openstreetmap.org/?lat=13.394&lon=-16.358&zoom=11&layers=B000FTF http://www.openaerialmap.org/?lat=13.42284&lon=-16.56708&zoom=11&layers=BF I have not tested the same settings at other places, but it does at least indicate that automated tracing from selected Landsat data could be possible. - Gustav
