I have two polygons: Polygon 1 and Polygon 2.
Using two metrics, area and perimeter length, I want to express quantitatively that Polygon 1 has a more uneven/jagged/irregular perimeter than Polygon 2.
Each polygon has the same perimeter length but each covers quite different areas. To quantify the unevenness/jaggedness/irregularity of each polygon, should the calculation be:
I thought perimeter/area, but then I found this blog post which uses area/perimeter : http://www.r-bloggers.com/measuring-the-gerrymander-with-spatstat/
