Problems with elevation #3

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
The gpx elevation data is incorrect. It'll usually double my climbing and 
descending accumulated meters. Yesterday, for example, I rode 70 km, which made 
me ascend and descend around 500 meters. That's what was displayed in the 
GPSport 260 Pro screen at the end of the ride.

Although, when generating a gpx and running a script over it which sums the 
amount of climbing and descent, it goes as far as 900 meters. The same happens 
when I upload it to Runtastic, so I think the problem is not with the script. I 
also notice suspect elevation in the gpx, because I started my ride at 965 
meters and the first record of the gpx regarding elevation is beyond 970 
meters. Finally, I also compared these info to the info generated by a Garmim 
Edge and the Garmim computes the 500 meters correctly.

I already took a look at the source code, but I couldn't find anything that 
would look like some sort of formula for elevation calculating.

Oh... And using or not using '-a' generates exaclty the same altitude info.
