I'm trying to apply a NDVI display to a mosaic dataset. I am trying to use the band arithmetic raster function but the results aren't what I'm expecting. The images I'm using are 4 bands:
Band 1 = red
Band 2 = green
Band 3 = blue
Band 4 = infrared
There is a built in NDVI calculation for the band arithmetic funciton and I'm trying to use that. However, when I apply it, all I get is a black image, not a range of values from -1 to 1.
If I use Raster Calculator and apply the NDVI formula using bands 1 and 4 of the original .tif image, I get the expected results.
I'm wondering why I can't get the NDVI band arithmetic function to work with the mosaic dataset...?
