[osg-users] osgdem: altitude value of the destination database

[Welsch, Michael, HRD/AB]

Hi,

I'm using osgdem to process heightfields. 

The resulting database's VertexArray has values of latitude, longitude
in degree (offset defined by the matrix) and an altitude value.

The altitude values are kindly strange. They don't seem to be (kilo)
meters or feets (Mean Sea Level).

Does anyone know what type of data the altitude values are (unit,
reference point) ?

Example Data:
9.66 E 46.33 N, altitude value: 0.0214596633 (should be about 2400m -
Mean Sea Level)



With kind regards,

Michael
