The Swedish Maritime Territory and Maritime Zones Act (2017:1272) applies from 1 March 2018
Baselines and boundaries are reported with all coordinates in annexes to the Act. The lines defining the boundaries have been divided into shorter segments to be correctly accounted for in existing map projections.
Baseline points, points on the low-water line and the low-water lake have been inspected and measured and form the basis for the calculation of the boundary of the maritime territory in the sea and the boundary of the adjacent zone. Straight baselines run between baseline points located on the low-water coastline (-0.5 metres RH2000) and follow the main direction of the coast. Normal baselines occur along certain parts of the coasts of Skåne, Öland and Gotland and follow the low-water line along the coastline where we do not have straight baselines. The points on the low-water line are located on normal baselines and have been selected where the position is expected to affect the calculation of the boundary of the sea territory. Low-water inserts are located outside the baselines and have been selected on a corresponding basis.
The following attributes are located in the point shape file:
Ordernr_parts — Reference number of the baseline points (BP) for the respective sub-distance.
Sub-distance — the baselines are presented with the following sections: Land and Öland, Gotland including Fårö and Lilla Karlsö, Gotska Sandön, Stora Karlsö, Brand, Brandshällarna.
Point number_name — Number and name of baseline points and low-water inserts
Latitude & Longitude — All points along the boundary are described by geographical coordinates in latitude and longitude expressed in the reference system SWEREF 99 partly in degrees and decimal minutes as stated in the law and partly in decimal degrees.
Point type — The following point types exist:
• point on the low-water line along the normal baseline (LP);
• end point at right base line, baseline point (BP);
• segmented point on a straight geodetic line between two baseline points
(MP), and
• point on low-water lakes located outside a baseline (LS).
Type of baseline — The type of baseline (right/normal) starting at the point.
