In **Shapely** the **distance** is the Euclidean **Distance** or Linear **distance** between two **points** on a plane. However, if we want to calculate the real **distance** on Earth's surface, we need to calculate the **distance** on a sphere. ... Now instead using a single coordinate-tuple we can construct the line using either a list of **shapely** **Point** -objects or.
