I have two feature classes of hexagonal polygons, both derived from a universal coverage of hexagons, both containing values for the exact same attribute.
What I'd like to do is create a new polygon feature class that contains the difference in absolute value for the attribute for each hexagon. E.g. a Manhattan polygon containing the 1990 population attribute (1,487,536) compared to a Manhattan polygon containing the 2010 population attribute (1,585,873) outputs to a third Manhattan polygon containing the difference in population (98,337).
Looking for a tool or function that performs this kind of Feature math (akin to Raster Math).
