So, I guess I'll forget the idea to fully automatise the process of
Landsat
border trimming? Can't we just have all of the Path-Row tiles ready
in a
compressed GRASS format? Some sort of packed ASCII file which can be
easily
imported? No other ideas?
I think you can trim the borders using the Landsat raster data
themselves: according to the metadata, valid numbers are > 0. If the
sum of all bands is zero, the pixel is outside.
If valid numbers > 0, why does the sum of all bands have to be zero ?
Normally, all bands are aligned, so in my understanding any 0 can be set
to NULL, or ?
