momepy.linearity

momepy.linearity(geometry)

Calculates the linearity of each LineString

The linearity is defined as the ratio of the length of the segment between the first and last point to the length of the LineString. While other geometry types are accepted, the result is not well defined.

\[\frac{l_{euclidean}}{l_{segment}}\]

where l is the length of the LineString.
