Arctic shoreline displacement and validation data for two pilot study areas
Description
Arctic shoreline displacement data for two pilot study areas are supporting information for the paper Nylén, Calle-Navarro and Gonzales-Inca: Arctic shoreline displacement with open satellite imagery and data fusion – Pilot study 1984–2022. The two study areas are:
- Tanafjorden: a low-arctic meso-tidal fjord coast in mainland Norway
- Ny-Ålesund: a high-arctic micro-tidal glaciated coast in north-western Svalbard
The study areas are 2500 km² each.
The dataset includes following files:
- Calculating_coastal_landcover_timeseries_summaries.R: code for summarizing the coastal land cover time-series in the R software.
- Calculating_shoreline_timeseries.R: code for calculating the shoreline by fitting and smoothing a polyline to the land cover raster in the R software.
- X_timeseries.tif: a multiband GeoTIFF raster file, with each band describing coastal land cover during one of the eight time-steps (1984–1988, 1989–1993, 1994–1998, 1999–2003, 2004–2008, 2009–2013, 2014–2018 and 2019–2022).
- X_summary.tif: a multiband GeoTIFF raster file, with bands that summarize the time-series from different viewpoints. These summary variables are: probability of belonging to the land class, long-term trend (between 1984-2003 and 2004-2022), change intensity, first time-step in water class, last time-step in water class, first time-step in land class and last time-step in land class.
- X_shoreline.geojson: a GeoJSON vector file, consisting of polylines for the shoreline during each time-step. The attributes of the polyline layer describe the time-step and the total length of the shoreline.
- NyAlesund_timeseries_REDUCED.tif: a reduced time-series for the Ny-Ålesund study area, including only the time-steps with adequate number of observations (i.e., excluding 1984–1988, 1994–1998 and 2004–2008).
- X_reference_shoreline.geojson: a GeoJSON vector file including the manually digitized (scale 1/5000) reference shoreline corresponding to the time-step 2019–2022.
- X_validationpoints.geojson: a GeoJSON vector file including 2000 random points (within 2 km from the reference shoreline) that have been manually classified into water and land. The classification corresponds to the time-step 2019–2022.
