One Coastline for Global and Continental GIS systems

This application allows you to visualize and download coastline data. The method is described in the Journal of Coastal Research in 2015. The data are a restructuring of the GSH global coastline. The restructuring is done with the IHO definitions of the Oceans and Seas in mind and currently limited to the seas and oceans around Europe. Restructuring implies that the coastal segments are starting and ending on the coastline as defined by the IHO and are directed clockwise. The intelligent restructuring allows for quick coding of coastline related data such as buoys, ARGO measurements, river outlets, islands etc. Such hydrographic coding can be downloaded as well from this site. The seas that are currently available are listed below:
