Any ideas?
First step (I think) is to analyse the _likely_ density of roads/buildings/whatever in a given km square - then compare OSM coverage within that square against that. Things you could use to find out the density: - Colour analysis on aerial imagery (e.g. Landsat) - Terrain - watery/hilly areas less likely to be dense - Compare against other free datasets (e.g., for the UK, density of postcodes on NPEmap) cheers Richard _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
