Bounding Circle

For each input geometry this node generates the minimum bounding circle that contains all its points. The minimum bounding circle is determined by finding the two points that are farthest apart, and the center and radius of the circle are calculated from these points.

The node is based on the GeoPandas project and uses the following related information and functions:

Options
