I completely agree with you, though. The trace from my cellphone is horrifically bad compared to that of my GPSMap60, so I still use the latter a lot for mapping.
What phones are you guys using? The TI chips Nokia uses seem to usually get within about 10 feet or better anywhere where there's a reasonable view of the sky. That's not to say it's never off, but the outliers are usually plainly obvious when looking at the track in JOSM. When I go out and map new subdivisions, there is often dirt work shown on the aerial imagery that can be used as a reference, along with the pictures from the phone taken at 5 second intervals, so I can be pretty certain it's close at worst. I could do better with a better GPS, I'm sure, but for your typical suburban-style development the phone seems as good as anything that doesn't involve post-processing. If I were trying to map individual structures, it probably wouldn't be good enough. However, for getting the roads on the map, my N900 works (or more accurately worked, given my recent output) just fine. -Nathan _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
