Selectable altitude source for "Height above ground"

[Holton181]

Hi,



First of, thanks for all hard work you put on the development of this excellent app, and adding a lot of suggested features given by us users!

Quite recently I discovered a small one that I know was requested long ago, and I assume it was added almost equally long ago but without me noticing until now. It's the dashboard control "Height above ground". For us non-commercial pilots it's a good rough indication of ground clearance.

Now to my request:

At the moment "Height above ground" is always using GPS altitude. I would like to be able to use the barometer altitude given by either internal or external barometer. Of course in an aircraft one always have a certified barometric altimeter so one can rather easily make sure the barometric altitude in Oruxmaps to be the same.



Thanks again!
