Multi band imagery processing
« on: June 19, 2019, 06:50:15 PM »
I am processing a 6 band imagery data set from Altum....

As one of the outputs, I create a NDVI index map using raster calculator with output band 4 as (B5 - B3) / (B5 + B3).

So index values vary from 0 to 1...

But when I move the cursor over output NDVI map, sometimes I get values in 29 000 to 31 000 range displayed in bottom right of screen which correspond to output band 5 LWIR...

Why is this so?
Best Regards,

Paul Pelletier
