Hello
This shouldn't be a problem since the ele tag should be in meters above sea level [1] and, according to swisstopo, elevations above sealevel and elevations in CH1903 should be about the same with meter accuracy [2]. Taking into account that the GPS as a source of elevation is incredibly inacurate, I wouldn't care too much if the ele=* height is in WGS84 or in CH1903.

I dare say that most of the ele tags in Switzerland are taken from the hiking posts at the moment, so I'd keep the CH1903 data for consistency. Maybe we should add a note in the wiki somewhere?
Actually that would make the data inconsistent with the rest of OSM then, wouldn't it be better to do ele=* for WGS84 and ele:ch1903=* ? _______________________________________________ talk-ch mailing list talk-ch@openstreetmap.ch http://lists.openstreetmap.ch/mailman/listinfo/talk-ch
