load_dem

Load DEM data from a list of tiles, crop and merge using a given bounding
box to create a raster DEM for the specified region. Results are cached, so
that new queries with the same input parameters will be loaded from disk.

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.
