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!

You're probably not culling the header before reading the image. I just tried it and it loads fine in Photoshop as a 32 bit file when you tell it the header is 69124 bytes. One needs to apply a stretch, obviously, to get an image with visible contrast. Moreover you may be confusing the line and the sample. Lines = height. Samples = width.
