The | '''For Scotland/England boundaries:''' The UK Continental Shelf (UKCS) comprises areas of the sea bed and subsoil beyond the territorial sea over which the UK exercises sovereign rights of exploration and exploitation of natural resources. The Continental Shelf (Designation of Areas) Order 2013 (made 31 March 2014) delineates the shelf and replaced two previous Orders, dating to 2000 and 2001 that had been made under powers in The Continental Shelf Act 1964. This is modified version from the UKHO Law of the Sea department data, available via https://www.gov.uk/guidance/inspire-portal-and-medin-bathymetry-data-archive-centre. | ||
'''For all other boundaries:''' | |||
Maritime Boundaries and Exclusive Economic Zones from the VLIZ Maritime Boundaries Geodatabase. Boundaries have been built using information about treaties between coastal countries. When treaties are not available, median lines have been calculated. An exclusive economic zone (EEZ) is a seazone extending from a state's coast or baseline over which the state has special rights over the exploration and use of marine resources. Generally a state's EEZ extends 200 nautical miles out from its coast, except where resulting points would be closer to another country. This dataset also contains delimitation of overlapping claims, court rulings and joint regimes. | |||

The geometry errors and duplicates were fixed; and the geometry was simplified to implement the layer in the MSP Challenge. Both layers were reprojected to Lambert's Azimuthal Equal Area (EPSG:3035) projection, The UK boundary was split in 2: the English and the Scotish parts based on the 12 Nautical Miles (12M) limit - Scottish territorial seas - Territorial Sea Act 1987 / Scotland Act 1998 layer . The attributes table was also reduced; attributes with empty fields for all features were removed. | ||
