This plugin adds various functions expression to measure the degree of compactness of a geometry(ies) (Polsby–Popper, Reock, Skew, etc...)
This plugin adds some common ways to measure the compactness through function expressions
These functions are particularly useful to detect gerrymandering, evaluate the regularity of a parcel, lot, etc...
For an introduction on geometry and compactness, see the wonderful `Math for the people` course https://web.stevenson.edu/mbranson/m4tp/version1/gerrymandering-math-topic-compactness.html
