This function calculates the compactness ratios for the aggregated areas.
It checks whether the projection of a spatial polygons data frame is in lat/long format. If the check passes, the function assigns an alternate projection. The spatial polygons data frame is then used to calculate compactness ratio. The function returns a vector of ratios.
calculateGATcompactness(myshp)A spatial layer.
