i did not find a bugtracker or any mention of one. So i'm trying this
one here. Maybe i'm just doing something wrong.
Today i created a bunch of tracklogs with a Wintec 202 (tes-files). For
the first time, i actually cared about the altitude information. Usually
i'm just clamping the tracks to the ground.
I did two conversions (one to GPX, one to KML using GPSbabel 1.4.4), and
in both, the altitudes were far off. Not only were they off, they were
actually the wrong way round?
Actual height profile from Google Earth:
Recorded height from Wintec, converted to KML:
The track starts in the upper left corner. I was riding a bus, wich went
downhill. So i'm pretty certain that the Google Earth profile from the
first image is more or less correct.
If anyone cares to take a look, here's my original recording as well:
And the conversion being displayed on Google Earth in the screenshot:
