Apply NDVI to Mosaic Dataset

Question asked by boyle.matt on Jul 31, 2014

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...?
