[Marble-devel] Review Request: AltitudeModel, altitude-profile plugin, srtm2 tilecreator

>  I got the feel that the word "elevation" is preferably used whenever in German we are using "Höhen..." (like the technical "Digitales Höhenmodell" which is "Digital Elevation Model (DEM)" as a technical term, or "Höhenprofil" = "Elevationprofile", etc.)
> I think that "altitude" is preferred whenever it's just "Höhe" in German.

Regarding your last paragraph: in practice most use cases will deal with
elevation. So elevation is ok imho.
