Description
Spatially designing and planning urban transformations around rivers while capturing the complexities of riverside urban areas remains challenging. An essential part of the challenge is how boundaries are drawn in the analysis of urban areas surrounding rivers. To overcome this challenge, we developed the rcrisp open-source R package to automate the morphological delineation of riverside urban areas—i.e., spaces where social, environmental and economic phenomena are assumed to be influenced by the presence of the river. Delineations following this method enable integrated local analyses, in which data from different sources must be combined within a neutral spatial unit, as well as global cross-case analyses, which require a spatial unit comparable across different geographic contexts.
The package includes functions to delineate the river valley, the river corridor, the corridor segments, and the river space (i.e., the area between the riverbanks and the first line of buildings) as well as an all-in-one function that runs all desired delineations. The resulting delineations can be used in any downstream analysis of riverside urban areas that benefit from consistent, comparable spatial units, including land-use, accessibility, and ecosystem services assessments. The package also includes functions to download and preprocess OpenStreetMap and global Digital Elevation Model data, which are required as input data for the delineation process.
With this poster, we aim to present the method, its implementation in rcrisp, and to demonstrate its broad applicability with use cases from different fields.
