There is a specific script in FlightGear that enables the calculation of the elevation at a specific longitude and latitude. The script is called find_elevations.pl and under GNU/Linux, for instance, this script is located at: /usr/local/src/flightgear/scripts/perl/examples/find_elevations.pl.
To use it:
- Launch FG like this : "fgfs --fdm=null --telnet=5401"
- Then, in a separate windows, lauch the script : "./find_elevations.pl".
- Enter the longitude and latitude of the object for which you want to get the elevation.
For instance :
olivier@olivier-portable:/var/www$ ./find_elevations.pl -3.926816 48.632452 62.37586682
For a longitude of -3.926816 and a latitude of 48.632452, the elevation is 62.37586682.
Enjoy !
