ArcGIS Pro 2.6: How to identify which band is which?

 

For example, in the screenshot below, the raster has 4 bands. How to identify which band is blue, red, green, infrared, etc.?

raster

The input raster.

Raster
nir_band_id

The band ID of the near-infrared band. The ID index uses one-based indexing.

(The default value is 4)

Integer
red_band_id

The band ID of the red-edge band. The ID index uses one-based indexing.

(The default value is 3)

So unless you have changed how the rasters are ordered, then by convention, nir would be 4 and red would be 3

Thanks Dan.

 

As bands are labeled with band#0, band#1, band#2 & band#3, then is it assumed that they are equivalent to band#1, band#2, band#3 & band#4 respectively?

 

Is there any other way to check which is which so that we can make sure that (in my raster):

 

band#2 = Red

band#3= Infrared

There is no band 0 in remote sensing, that image is just showing 0-based numbering... so add 1 to get your bands

But what the values of RGB represent in the screenshot below?
