[GRASS-dev] how to apply a processing to a group?

[Yann Chemin]

Hi,

was wondering...

Say somebody imports a hyperspectral/hypertemporal image (i.e. AVIRIS
/ Modis8days comp for 2-3 years) and wants to process all the bands
simultaneously.

Simpler(?)
---------------
Is there a way to apply a simple set of equations to the group itself,
bands belonging to the group would then inherit the equations.

More complicated (maybe?)
--------------------------------------
is there a way to select a root name (say modis_ref_2* and
modis_ref_1*) and apply a beloved NDVI to the the pair matching
extensions.

is there a way to use group directly for display? (i.e. d.rast
group_name=blabla mode=rgb combination=4,2,1).


thanks,
Yann
