CRiSp implements a spatial morphological method of delineation (Forgaci, 2018) that considers both the terrain of the river valley and the urban fabric, as shown in the diagram below.
The method consists of three steps, each explained on this website in a separate article:
- The corridor boundary of the urban area surrounding
the river is delineated on the street network considering a given
walkshed (the urban area reached along the street
network within a given walking distance from the river, 500m by default)
and the valley edge derived from a digital elevation
model, as shown in
vignette("corridor-delineation"). - The delineated corridor is divided into corridor
segments bounded by the main transversal streets, as shown in
vignette("corridor-segmentation"). - The river space, i.e., the space between the river
and the first line of buildings is determined, as shown in
vignette("riverspace-delineation").
