Hi,
we have a set of tiffs georef with 4th bands of color RGB and Infrared.
We need to activate a wms with the color from the NDVI index
NDVI = Normalized Difference Vegetation Index
NIR - RED
NDVI = -------------
NIR + RED
Where NIR is the 4th band,
RED s the 1th band.
We prefer dont' do a physical float raster, but retrieve this realtime from the
original tiffs.
I try to reproduce this index NDVI using to a LUT table in MapServer,
but without any success.
There is some other solution to obtain this on mapserver.
Thx to everyone.
