Hello!

I have a question regarding multi-band raster layers.

Currently I have published a raster with 4 bands: Red, Green, Blue, NIR. I
want users to be able to see both the RGB as a NDVI health index. However
for the latter I would need to do a raster calculation with both the Red
and the NIR.

Is there a way to make geoserver do this calculation?
Can geoserver create a new band from multiple existing bands?

Kind regards,

Thomas
