(2019) ) and rivers (for more details, see Cohen et al. (2018) ). 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. 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 - family-names: Matos given-names: Gonçalo email: goncaloafmatos@tecnico.ulisboa.pt orcid: https://orcid.org/0009-0001-3489-1732 repository: https://ropensci.r-universe.dev repository-code: https://github.com/ropensci/slopes commit: 1ff703b855ecb6b033a936dbdb72538f36269f4e url: https://github.com/ropensci/slopes/ date-released: '2025-09-12' contact: - family-names: Lovelace given-names: Robin email: rob00x@gmail.com orcid: https://orcid.org/0000-0001-5679-6536
