An algorithm and implementation for calculating the areas of overlaid polygons without calculating the overlay itself, is presented. Overprop is useful when the sole purpose of overlaying two maps is to find some mass property of the resulting polygons, or for an areal interpolation of data from onemap to the other. Finding the areas of all the output polygons is both simpler and more robust than finding the polygons themselves. Overprop works from a reduced representation of each map as a set… CONTINUE READING
