Function to obtain the digital elevation models for the active floodplains along the German federal waterways Elbe and RhineSource:
This function downloads and patches the tiled digital elevation models (dem) along the German federal waterways Elbe and Rhine that have been published on pangaea.de.
Since the underlying tiled digital elevation models (dem) are rather
large datasets hydflood provides options to permanentely cache these
options("hydflood.datadir" = tempdir()) is the default. To
modify the location of your raster cache to your needs set the respective
options() prior to loading the package, e.g.
options("hydflood.datadir" = "~/.hydflood");library(hydflood). The
location can also be determined through the environmental variable
Since downloads of large individual datasets might cause timeouts, it is
recommended to increase
