HOW TO
Instructions provided describe how to get more accurate results from the Zonal Statistics function. Running the Zonal Statistics Spatial Analyst function with features as the zones gives a result that overestimates the number of cells that fall within a polygon. This is because features are converted to raster as part of the processing. Cells that only partially fall within the boundary of a certain feature are included if the cell is encountered first in the conversion processing.
