slopes: Calculate Slopes of Roads, Rivers and Trajectories

Calculate the slope (also known as steepness and gradient) of linear features such as roads, rivers and ski routes.

Value

The package does not return a single value, but a collection of functions.

Details

Created by Robin Lovelace and Rosa Félix, who developed the package to support their research in active travel, and the prioritisation of investment in cycling, an activity which is sensitive to slopes, in particular.

See https://github.com/ropensci/slopes/ for the source code and https://docs.ropensci.org/slopes/ for the website.

All package functions can be found in the Reference page on the package website.
