<speed> in gpx file
« on: July 08, 2013, 12:43:10 »
Hi,
I'd like to know what the <speed> node refers to when exporting a track to GPX.
As a matter of fact, all the information provided in the track description is correct (e.g. "max speed - 150 km/h"), but the speed given in each the <trkpt> in the GPX is never higher than 37 or so.
I set Locus to work exclusively in km/h, so what is the unit used in the GPX file?
Is this information reliable?

thanks,
Cedric

unit in speed tag should always be in metres per second. In GPX is no place to specify units (and it's should be quite weird if every GPX file has own units), so all values are in base units - metres, seconds

ahahah... I'm so stupid....
For a change, the official unit system is used and I don't even think about it :)
Thanks Menion for opening my eyes facing this evidence...
