Hi(gh)!

I would like to generate POV-Ray meshes from PDS altimetry data files (for example the global Vesta file from Dawn Public Data) - but I have no clue what data format they contain... obviously, its binary, simple cylindrical projection, based on a 255 x 255 x 255 kms sphere (Vesta), 32 bits per data point. But what data format - int or float? Signed or unsigned? Big or little endian? Where do I get detailed information on the format of these PDF files?

See you in Khyberspace!

If you really need to do it in C/C++, I can send you the source of a converter I wrote near 10 years ago that can handle it and converts it to FITS format. But this is generally not the optimal solution and it is better to use img2png (although as far as I know, Bjorn has yet to port it to Linux) or just read the raw data using GIMP or ImageJ as pointed above.
