Hi Susie,
Thank you for noting that the SKYV* files are not peer reviewed.
I was able to process the SKYV_65N_240M image in MATLAB. The fread function enables to read from an open binary file. From the LINES or FILE_RECORDS line of the label I'm able to determine the size of the array.
fid = fopen('SKYV_65N_240M.IMG');
data = fread(fid,[LINES, LINES], 'int16','ieee-le');
After applying the formula DN*SCALING_FACTOR+OFFSET, where SCALING_FACTOR is 0.0002 and OFFSET is 6.2832 , the resulting array looks correct and is in a range of steradians.
It seems that is the process for processing any PDS IMG file type. Is there a bit of detail that I'm missing from reading in the label?
Thank you for your help.
