Dear All,
Is there anybody out here, who has ever used the MODIS cloud mask with
250m resolution in IDL?
If so, I was wondering if you could give me some hints about how to
acces the two last bytes of the
cloud_mask SDS where the 250m binary thing is suppose to be stored.
and then how to use it to
mask my 250 m modis image. I am really struggling to do that, so some
help would be really appriciated.
best regards
Yoann

I think you can write an IDL program to change the byte data to binary data,and then extract the two last bytes.
