[closed] height difference

[alexlong]

Hi. I was asked to make a post here:

I recorded a track moving on a plain surface, with no elevations, but I can see 30 meters hight difference on the track. Is this a way GPS or AlpineQuest works? In case of AlpineQuest do I need change anything in the settings?
A message link with a screenshot is here http://4pda.ru/forum/index.php?s=&showt ... p=70437819

Hi Alex,
It's due to the inaccuracies of the GPS. It's even more inaccurate when you have not a clear access to the sky like in woods or with thick clouds.
In order to get a more precise elevation you can use a device with a pressure sensor so the application will use barometric elevations which are more precise.
You can also use an external bluetooth GPS and record it's location from AlpineQuest.
Hope it helps.

Thanks, it's clear.
