I want a quantification technique to differentiate different shapes of polygons. For example, the following image consists of 3 seperate polygons, e.g., (a) is stretched to its tails, (b) is bowl shaped, and (c) is a complex polygon.
Is there any geometrical way to differentiate these phenomenon?
For instance, if I want to segregate only the bowl shaped polygons, what would be the technique in GIS?
I dont want to use any kind of pattern recognition techniques, just looking for a geometrical solution in ArcGIS.
