Hello,
I am currently working on reading the UVL (linearised) UVW (XYZ) Surface Normal files, so as to get an idea of rock/soil facet orientations. I have developed a Matlab code to read these files with their main IEEE4 binary encoded data. I was wondering if there was anywhere where I could read more on these types of files and how to interpret them. For example I'm getting, for a specific pixel, in the three bands:
band1: 0.06
band 2: 0.25
band 3: 0
and I can't work out what they are. Are they values in the three axis XYZ that define the surface normal vector? , in that case , in what coordinate frame are they determined?. Also I would like to know the difference between these files and the UVW (XYZ) Surface Normal files.
Thank you very much for your time,
Mike
