I am working with the image below and I am trying to find how many pixels are in the grey corners of the image, and I want to assign them a probability of 5%. The bottom layer is my DEM and the top layer is a raster of distances. I know how many pixels I have on my raster layer, however I am not sure of how I can get the pixels outside of the circles and how to assign those pixels a probability. I would appreciate any help I can get!
Follow these steps in ArcMap 10:
Based on this analysis, you can say there is a 0.3 probability that a randomly selected pixel within the extent of your DEM will fall outside of the rings, yet within the DEM raster (i.e. assuming the cell size is the same for both rasters). I hope this helps you.
