I have a large number of rasters with 3 bands (R,G,B). What I want to do is add all 3 bands of each raster together to end up with a single band image with the summed R,G,B values in each pixel but I'm not sure how to do this in ModelBuilder. Do I have to somehow split each raster first, then add each one?
How would I iterate through each band of every raster?
Edit:Basically this is what I have so far. Right now it will take 3 bands of 1 raster and add the bands then go on to create a polygon of a certain reclassed area. I want to do this on a large number of rasters but am unsure of how to make it work.
