I have a 4-band ortho with near infrared in the fourth band. I've used the fourth band as red.
I know from being on site that there is a creek at the yellow line and some standing water at the white line. And I can see it in the ortho, too.
Using a raster function, I want to highlight the known waterbodies, as well as other unknown waterbodies, in a bright colour. I've tried using the NDVI raster function, but none of the NDVI options highlight the water. Only the vegetation seems to be pronounced in the output NDVI layers.
Can a raster function be added that can highlight water in a bright colour? I can send the .tif ortho file to Esri staff in a private message or email if needed.
