IMHO, the outlines of all buildings and parks etc. /should/ be mapped in detail, but won't be because that's too much effort for most mappers. Marking the building with just a node is better than leaving it off the map, and good enough for most uses of the data. I have only found it possible to measure a building outline based on aerial imagery - I've not managed to get a good enough image from a GPS. I'm hoping that one day, video mapping (using match-moving as well as GPS) may help. http://en.wikipedia.org/wiki/Match_moving http://en.wikipedia.org/wiki/Structure_from_motion See also PTStereo (http://www.panotools.org/) Robert (Jamie) Munro -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFH5v1Tz+aYVHdncI0RAhvEAJ9q7o4zf/FNd/oby3alJy5Zgk+6AACg+8mr TAmhwdI48KojUAb2Tpif5qg= =anWn -----END PGP SIGNATURE----- _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
