title: SCShores: time-series of shorelines from Spanish Sandy beaches from citizen-science monitoring program.

description: This repository contains 5 years of sandy beaches shorelines deriverd from a citizen-science monitoring program in the Spanish coast. The methodology and the dataset are described in:

González-Villanueva, R., Soriano-González, J., Alejo, I., Criado-Sudau, F., Plomaritis, T., Fernàndez-Mora, À., Benavente, J., Del Río, L., Nombela, M. Á., and Sánchez-García, E.: SCShores: a comprehensive shoreline dataset of Spanish sandy beaches from a citizen-science monitoring programme, Earth System Science Data. V. 15, 4613-4629 , https://doi.org/10.5194/essd-15-4613-2023, 2023. 

The shoreline dataset is provided in 1 GEOJSON file: SCShores.geojson. This dataset covers five sandy beaches located on the Atlantic and Mediterranean coasts of Spain where CoastSnap stations were available, and it includes a total of 1721 shorelines. The coordinate system for the geospatial layer is WGS84.



SCShores.geojson: this layer contains the sandy shorelines . Each feature in this layer is a multipoint with the following attributtes:



site: CoastSnap station name id, e.g. agrelo, samarador, cadiz, ….

date: date and time of the shoreline, yyyyy-mm-dd hh:mm:ss

timezone: Coordinated Universal Time, UTC

timestampQuality: quality flag indicating the confidence in the date-time indicated by the image provider, e.g. 1, 2

imageSource: source of the original image from which the shoreline has been derived, e.g. Instagram, Twitter, Facebook, Email, CoastSnapApp

elevation_m: same as Z coordinate, defined by the observed tide and the tidal offset, in meters, Tide+tide offset

verticalDatum: mean sea level in Alicante, which is considered the zero topographic reference in the Spanish territory, NMMA

geometry: type of geometry used in the file, MultiPoint

coordinates: Geographic WGS84 coordinates for each point in the geometry, longitude, latitude, Z
