Lineage The maritime boundaries and areas are calculated from the baselines. In the Maritime Boundaries dataset, the baselines used were a combination of a coastline as a proxy for the low-water line (the normal baseline described in UNCLOS) and straight or archipelagic baselines. The source for the straight baselines was primarily the United Nations repository of all the claims from UNCLOS’s signatories: DOALOS. In addition to this main source others were also used to complete the straight baselines database such as national legislation on maritime delim-itations, agreements, treaties, USA Department of State, among others.
