WebbShapely uses a cartesian plane system for computing geometries (distance = euclidean distance) Shapely does not support coordinate system transformations. All operations on two or more features presume that the features exist in the same Cartesian plane.

In the case of the infinite regions, do this by splitting the point at infinity into two points that are far enough away, joined by an edge. ("Far enough away" means that the extra edge passes entirely outside the bounding polygon.)
