I'm working with ArcGIS Pro 2.4.0. I have a raster dataset consisting of several plots of crops. Within each plot, there is a small ground target that has differing reflective values than the surrounding crop. Since I am trying to extract the mean pixel value of the plots, I don't want the higher reflective values of the targets to skew the mean.
Here is a plot I am working with:
"A" denotes the main plot boundary, whereas "B" denotes the boundary around the reflective target.
How can I set all the pixel values within B to null? I've tried a SetNull equation, but typically the SetNull procedure involves setting all pixel values above/below a set value to null. If the solution lies within building a conditional statement, I'm not quite sure how to do that.
