Re: [OSM-talk] Why does OSM need timestamps in gpx trails
Tanveer Singh wrote: I use a lowrance unit, and there are no timestamps dumped in tracks. When I convert to gpx, OSM refuses to accept the tracks! Why so? For mapping we just need lat/long, timestamps are not really needed? I know using some perl I can insert bogus timestamps, but thats inefficient and requires extra work. Can I understand the logic of this decision, and the though process behind it. If I want OSM to allow gpx trails without timestamps, whom do I argue with? IIRC, the timestamp is used to indicate node order in the database. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

So you can get gpx data from tainted sources and still have timestamps. So all this is doing is stopping people with older gps systems to upload tracks to the database. Its just a hindrance, and in no way will stop tainted data in the osm. For example lets say somebody opens google maps, and then looks at the google maps, and maps osm, using copy by mind method. This is somewhat like DRM. Somebody with malicious intent can work around the system, and genuine users feel the heat. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
