We added a "roundness" method to QgsCurvePolygon
, allowing the calculation of the "roundness" of an area feature based on the formula Roundness = (4 * pi * Area) / Perimeter^2
.
This includes the addition of a new expression and a processing tool for calculating roundness. The processing tool creates a new layer with the roundness of each feature in a new field.
This feature was developed by Antoine Facchini
