  Straight baselines

In the Law of the Sea, a straight baseline is composed by a loxodrome connecting two points of the low-water line or low-tide elevations if there is a lighthouse or similar permanent infrastructure on them. The conditions to draw such lines are defined in Article 7 of UNCLOS.

The straight baselines are part of the baselines of a coastal State below which the internal waters are defined. Those straight baselines, in addition with the normal baseline, compose the inner limit of the territorial sea and are the basis of the computations of the outer limits of other maritime spaces defined by UNCLOS. They are also composed of the closure line for bays and rivers in compliance with Aricles 9 and 10 of UNCLOS.

The objects of the theme "Straight baselines" result from Shom computations and are published by decree of the French Republic.

Statement

The theme "Straight baselines" is based on the basepoints defined by decree. When the geographical coordinates of the points are expressed in the legal reference in a geodetic system other than WGS84, they are converted into WGS84 with parameters and conversion formulae the most accurate Shom has.
