The implemented method was developed in Roalkvam (2023)\n for the Norwegian\nSkagerrak coast. Although it can be extended to other areas,\nthis also forms the core area for application of the package.\nShoreline dating is based on the present-day elevation of a\nsite, a reconstruction of past relative sea-level change, and\nempirically derived estimates of the likely elevation of the\nsites above the contemporaneous sea-level when they were in\nuse. The geographical and temporal coverage of the method thus\nfollows from the availability of local geological\nreconstructions of shoreline displacement and the degree to\nwhich the settlements to be dated have been located on or close\nto the shoreline when they were in use. Methods for numerical\ntreatment and visualisation of the dates are provided, along\nwith basic tools for visualising and evaluating the location of\nsites.", "Language": "en-US", "License": "GPL (>=
