About Terrain Database(Didn't got answere in forum)

[pankaj thapliyal]

Hello
I have actual aircraft data ( latitude,longitude,altitude,pitch
angle ,roll angle and yaw angle ) .These six parameters i am giving input
to FlightGear and i am trying to fly the aircraft but it is hitting hills
and going inside ground level.
thats why i want to ask about terrain database.
and what reference you are using to create terrain(eg. SRTM, NED etc ).

Flightgear uses WGS84 elliptical coordinates or the cartesian coordinates with
this WGS84 ellipse together with srtm elevation.
Where the landcover stems from is more complex, but should not harm for your
question.

Where do you feed your data? May be there is something in between?
