I have phr1a and phr1b images (Pleiades) and I need to make atmospheric correction. First, I tried to do this by using Envi FLAASH. by the way, I tried also ERDAS atcor but there was also same conversion problem. I did radiometric correction but I couldn't do atmospheric correction because every time the software has the error of ACC error:convert7. Does anybody have any idea how to overcome this problem?

FLAASH in envi is very sensitive.

1) your result must be saved in other drives (not drive C). 2) you should make a folder for saving FLAASH result specifically. 3) you should enter any name as root name, because the root name box in empty. 4) you should enter a single address for output reflectance file and output directories.

good luck,

  • Why can't it be saved to a location on C?, seems a major drawback if your PC only has a C: drive. Perhaps it can only be save to drives that have public write?
