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?

From the symbology, the bands representing the RGB channels are set. For example, in the screenshot below, Red is assigned to Band 4, Green to Band 5, and Blue to Band 7.

Additionally, the datasheet of the imagery should indicate what each band represents
