Re: [OSM-talk] High-Precision GPS Survey Equipment?
Hi I use normally a EGNOS/WAAS submeter DGPS, often for OSM mapping. :-) My DGPS run really well only in optimal conditions (no satellite obstruction, multipath, etc.), but I observed that the performance in a urban environment is normally lower than a "normal" bluetooth GPS based on a Sirf III or a MTK chipset. I think that one of the keys of these cheaper GPSs are the better sensitivity than the most expensive DGPS, as well as the algorithm for calculating the position (myDGPS uses also carrier for decoding the signal).

Re: [OSM-talk] incomplete tags sac_scale
I think it is related also to some problems of tagging with JOSM: in JOSM, the predefined values for sac_scale are uncorrect tags (in the version I downloaded 2 weeks ago - I don't know if this problem is now solved) Ciao Alberto ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Hiking, for me, is like a highway for pedestrians, quite large (but not enough for a track) and more or less flat or nearly flat. Mountain_hiking represent a normal path where you must have hiking shoes and is a "normal" and easy mountain path, also with differences in altitude. Demanding_mountain_hiking is when you start to use your hands only because the terrain is too steep, but you don't climb. This is the way I'm tagging a lot of mountain paths in the Italian Dolomites... Regards Alberto ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

The big problem is comparing the different national scales. For me, in the Italian Dolomites, it is easy to apply the sac_scale because reflects more or less the overall difficulties of all the paths (except for Via Ferrata / Klettersteig that is currently lacking a tag).
