In Finland it lot of bytes are used for lakes and forest roads which are interpreted from Landsat/Yahoo/OpenAerialMap imagery. Link http://wiki.openstreetmap.org/index.php/WikiProject_Finland is visualising the situation with highways. Landsat imagery is usable in sparsely inhabited northern Finland where minory roads can easily be distinguished from forest. Location accuracy is not very well, about +/- 50 meters, but better than nothing. People are also eagerly digitizing lakes from Landsat imagery: http://openstreetmap.org/?lat=65.94&lon=29.747&zoom=10&layers=B0FT This is almost never ending job, right now no more than 10 per cent of the lakes have been digitized. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
