[GRASS-dev] Feedback upon Landsat related modules

Alex,

I do have some modifications to propose:

1. It would be nice to use the official WRS2 Path/Row tiles as MASKs with the "-
m" (or another, newer) switch, so the module works through all bands of a 
scene and trims them based on the MASK. It would take for the users to get the 
Path/Row tiles of his interest, import them and, perhaps rasterise them 
(although this last step can be integrated in i.landsat.trim).

What do you think? How difficult would that be?  Also, this means that both the 
rast_buffer and the gener_thresh parameters will be no longer used in this 
case. Right?

Currently I am doing this work for many Landsat scenes -- scripting or one-
liners in bash as this is the fastest way for me.

2. The way the "output_prefix" parameter works (e.g.: "Prefix for output raster 
map, Example: 'trim' generates B.1.trim, B.2.trim, ... "), makes me think that 
it should be actually named "output_suffix".

Best, Nikos
