Description
Summary:Dataset abstract This dataset is derived from: - The GPS track of the R/V-Akademik Tryoshnikov (10.5281/zenodo.3772377) - The shapefiles of the continents from NaturalEarth physical (@50m), version 4.1.0, downloadable at [https://www.naturalearthdata.com/http//www.naturalearthdata.com/download/50m/physical/ne_50m_land.zip](https://www.naturalearthdata.com/http//www.naturalearthdata.com/download/50m/physical/ne_50m_land.zip) - A manual entry of the smaller islands which may not be mapped on the NaturalEarth resource, namely: - "Peter I": [-68.8282, -90.6157] - "Scott": [-67.3783, -179.9117] - "Young": [-66.2833, 162.4167] - "Buckle": [-66.65, 163.05] - "Sturge": [-67.416667, 164.733333] - "Siple": [-73.65, -125] - "Bouvetoya": [-54.4208, 3.3464] The calculation of the actual distance to land has been done in qGIS 3.2.3-Bonn https://qgis.org/downloads/, using the NNJoin plugin version 3.1.2 https://plugins.qgis.org/plugins/NNJoin/. After the point-to-closest polygon distance calculation, the python script in src/add_distance_to_small_islands.py replaces the distance calculation to the centerpoint of the islands (as reported above) if the boat is closer to the island centerpoint than any other coast.
