Hi ;
Jean! thanks for your reply. Yes I test my machine and I have 4GB ram
and memTest shows that I can use this machine for my process. Just I
want to use 3 band and of course all LANDSAT ETM+ data are 8 bits.
Well what I shall do now? What is your propose to read this data and
can I use mosaic_doit in a for loop to add each time a new image to my
mosaic?
Cheers
Dav
