[GRASS-user] Quick note on EVI2 vs NDVI

[Nikos Alexandris]

Hi list!

Just wanted to drop a note on EVI2.  It looks and performs better than NDVI 
(tested with large Landsat5TM-based mosaics over Greece).  It sure helps 
visual discrimination of dense vegetation from the rest.

Will post screenshots at some point laaater (in the Wiki of course) -- using 
color=ndvi for both currently.

I wonder, however, if there a separate, tweaked, evi(2) set of color rules is 
required to get most out of it.

Best, N
