Actually, it was georeferencing an image with my phone against a benchmark in a cycleway through a swamp that made me realize how far off smartphones are in terms of GPS. The swamp, being mostly water, is of course, level, and without any tree cover or hills for nearly a half mile in any direction, and having been using the GPS for pedestrian navigation all afternoon, made me quite surprised to see the geolocation data for the photo (taken just inches above the benchmark) was off by almost half a mile. _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
