I just tried out the new i.vi in GRASS 7 and it doesn't seem to do anything.
I've tested it with the landsat images in the NC07 demo data set. I set the region to match the landsat images and ran: i.vi --overwrite viname=NDVI red=lsat7_2000_30@landsat nir=lsat7_2000_40@landsat green=lsat7_2000_20@landsat blue=lsat7_2000_10@landsat chan5=lsat7_2000_50@landsat chan7=lsat7_2000_70@landsat output=GEMI_lsat7_2000 I get a map with all 0's I got the same result with the GEMI and NDVI routines. Am I doing something wrong or is this a bug. Michael ____________________ C.
