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.
