Error on computed altitude with tcx files #48

Closed mt-from-sf-to-gh closed 2 years ago

mt-from-sf-to-gh commented 13 years ago

I observed altitude variations while loading a .fit or .tcx file corresponding to the same activity. I found the origin of the issue: the start altitude is 218 meters. But after loading the tcx file, the first altitude point is 0 and 218 for the second one. Then the cumulative altitude is biased with the 218 meters difference. Moreover, it\'s not possible to correct this with tools dedicated to the altitude correction.

In the tour editor, you can either remove the 1st time slice or you can set the altitude for the 1st time slice to 218

The first trackpoint in the txc file contains time but not other data, this is the reason why the 1st altitude is 0
