I'm a non-geographer using ArcMap 10.6.
I have a similar question to the two asked here: Weighted averages: accounting for grid cell surface variation in proportion to the cosine of its latitude
I have two raster files, one of terrain roughness index (TRI) and the other of cell size. Both correspond to a 30 by 30 arcsecond cell.
My question is how do I weight the TRI raster by the cell size raster? I have used the Zonal Statistics tool to calculate the TRI for each of my polygons without accounting for the cell size, is there some way to calculate the weighted average using this tool?
