Compactnesss tests polygons
WebCompactness can be quantified in several ways: 1) from physics, the moment of inertia of the polygon; 2) computations using polygon area and perimeter (or maximum length); … WebProperties of compactness tests It is important that compactness tests share properties for comparison: •Compactness “scores” are always between 0 and 1 •Closer to 0 = less compact, closer to 1 = more compact •“Invariant under scaling” –units such as miles or kilometers not relevant (tests will be ratios and units will cancel out)

WebArea-based compactness measures Compactness may be expressed as the ratio of the area of a shape to the area of some larger, enclosing shape. Two common measures are the Minimum Convex Polygon and the Reock scores. Minimum Convex Polygon is the ratio of the area of a shape to its convex hull. WebCompactness – Objects which have an elliptical shape, or a boundary that is irregular rather than smooth, will decrease the measure. – An alternate formulation: – The …
Webmodified compactness score, it would be possible to use a compactness test more effectively and fairly across all districts. Several methods of incorporating such data were explored with test districts. A Python script was created to apply the calculations behind the selected method to any polygon shapefile.
WebJun 1, 2013 · In brief, the compactness C can be defined as how close a shape is to a circle by comparing area (A) and perimeter (P) using this formula proposed by Li et al. [53]: Fig. 18 (b).
