SDS

This dataset of Satellite-Derived Shorelines (SDS) covers about 20 km of the Valencian coast (between the North of the Xuquer river and the Port of Gandia, Spanish Mediterranean) and is associated to 60 dates (06/07/2015 – 18/01/2018). These SDS are an example of those extracted for the work  “Cabezas-Rabadán, C., Pardo-Pascual, J. E., Palomar-Vázquez, J. M., & Fernández-Sarría, A. (2019). Characterizing beach changes using high-frequency Sentinel-2 derived shorelines on the Valencian coast (Spanish Mediterranean). Science of The Total Environment, 691, 216-231. doi: 10.1016/j.scitotenv.2019.07.084.”. If you use these data please mention the source.

The extraction process used the SHOREX system and the methodology described by Sánchez-García et al. (under review) and Palomar-Vázquez et al. (2018a, 2018b), sustained in the algorithm previosuly described by Pardo-Pascual et al., 2012 and Almonacid-Caballer, 2014. It used the SWIR1 band of the freely available Sentinel-2 imagery (Copernicus Open Access Hub), fitting a third-degree polynomial in order to detect on a 5×5 kernel the shoreline position with an estimated accuracy of 3.01m RMSE.

Date format (YYYYMMDD). Reference system: WGS84 UTM30N. Available formats: .shp and .kmz
