%description
Calculates the slope (longitudinal gradient or steepness) of linear
geographic features such as roads (for more details, see Ariza-López et
al. (2019) <doi:10.1038/s41597-019-0147-x>) and rivers (for more details,
see Cohen et al. (2018) <doi:10.1016/j.jhydrol.2018.06.066>). It can use
local Digital Elevation Model (DEM) data or download DEM data via the
'ceramic' package. The package also provides functions to add elevation
data to linestrings and visualize elevation profiles.
