The package was initially developed to calculate the steepness of street segments but can be used to calculate steepness of any linear feature that can be represented as LINESTRING geometries in the ''sf'' class system. The package takes two main types of input data for slope calculation: vector geographic objects representing linear features, and raster geographic objects with elevation values (which can be downloaded using functionality in the package) representing a continuous terrain surface. Where no raster object is provided the package attempts to download elevation data using the ''ceramic'' package.' authors: - family-names: Lovelace given-names: Robin email: rob00x@gmail.com orcid: https://orcid.org/0000-0001-5679-6536 - family-names: Félix given-names: Rosa email: rosamfelix@tecnico.ulisboa.pt orcid: https://orcid.org/0000-0002-5642-6006 - family-names: Talbot given-names: Joey email: j.d.talbot@leeds.ac.uk orcid: https://orcid.org/0000-0002-6520-4560 repository: https://ropensci.r-universe.dev repository-code: https://github.com/ropensci/slopes commit: 7f9ee5cd6dd0edcc8740c94c845165331a72df76 url: https://github.com/ropensci/slopes/ contact: - family-names: Lovelace given-names: Robin email: rob00x@gmail.com orcid: https://orcid.org/0000-0001-5679-6536
