[osg-users] How to validate the value of height Above Terrain

[Suraj Paul]

Hi,

I am trying to find out the height above a terrain (HAT).

Currently im reading terrain DEM in .ive format and using getHeightAboveTerrain() i m computing the HAT for given point (lat/lon and its altitude is available). 

I wish to check the output of my programme is correct by validating the obtained HAT results using another source. Any hints on this?

I am basically looking for a terrain DEM where its HAT at each location is already available so that i can match the HAT computation of my programme with it.

Any clues would be very helpful.

... 

Thank you!

Cheers,
Suraj
