clip_and_filter

Lines that intersect the river and that cross the corridor from side to side
are considered valid segment edges. We group valid segment edges that cross
the river in nearby locations, and select the shortest line per cluster.
From these candidate segment edges, we select the ultimate set of
non-intersecting lines by dropping the longest segments with most
intersections.

Provides tools to automate the morphological delineation of
riverside urban areas based on a method introduced in Forgaci (2018)
<doi:10.7480/abe.2018.31>. Delineation entails the identification of
corridor boundaries, segmentation of the corridor, and delineation of
the river space using two-dimensional spatial information from street
network data and digital elevation data in a projected CRS. The
resulting delineation can be used to characterise spatial phenomena
that can be related to the river as a central element.
