title: Shoreline change in coastal Natural World Hertiage Sites

description: This repository contains the data associated with the paper: Multi-decadal shoreline change in coastal Natural World Heritage Sites - a global assessment (http://doi.org/10.1088/1748-9326/ab968f). It contains: - 2020_transects_data_shorelines_linearity_geomorphology_final.csv: a dataset of transect-based shoreline and geomorphological datasets in 67 coastal Natural World Heritage Sites with available shoreline data. -2020_transects_data_shorelines_strong_linear_geomorphology_final.csv: a dataset of transect-based strong linear trends (recessional, depositional and stable) and geomorphological datasets in 59 coastal Natural World Heritage Sites with strong linear behaviour. Shorelines were derived from a global assessment of derived Landsat images (Luijendijk, A. <em>et al.</em>,2018,<em> </em> https://doi.org/10.1038/s41598-018-24630-6, Hagenaars, G. <em>et al., </em>2018, 10.1016/j.coastaleng.2017.12.011 and Hagenaars, G. <em>et al., </em>2017, http://resolver.tudelft.nl/uuid:34a0114b-5e39-4b52-9940-3a7e9f5a2982). Conditional and outlier data cleaning were undertaken on the raw shoreline dataset for further analysis. The geomorphological data have been obtained from the following datasets: <strong>Topography:</strong> Global Map DEM (2017) - https://globalmaps.github.io/ <strong>Land cover:</strong> Global Land Cover by National Mapping Organisations - GLCNMO (Kobayashi, T. <em>et al.</em>, 2013, 10.5539/jgg.v9n3p1) <strong>Coastal type:</strong> Worldwide Typology of Nearshore Coastal Systems (Dürr, H.
