Is there any MATLAB code to convert .btg file to .hgt file ??? If its available please post it asap...... I have seen the page http://wiki.flightgear.org/index.php/BTG_File_Format......Apart from this is there anything available? Let me know soon.............Thank you

.hgt is a simple array of height values.  .btg is FlightGear scenery format which includes terrain skinning, texturing, runway lighting, airports, etc.

If you want to do something with .hgt files, why don't you just download the original .hgt files and use them directly?

As far as I know, all our terrain processing tools are written in C++.
