river_buffer

The river geometry may consist of multiple spatial features, these are
optionally cropped using the area of interest, then merged after applying the
buffer.

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.
