Baselines

Description

The Act (2017:1272) on Sweden's territorial waters and maritime zones applies from 1 March 2018 Baselines and boundaries are reported with all coordinates in annexes to the Act. The lines that define the boundaries have been divided into shorter segments to be correctly reported in existing map projections. Baseline points, points on the low-waterline and low-water creeks have been inspected and measured and form the basis for the calculation of the territorial boundary of the sea and the boundary of the contiguous zone. Straight baselines run between baseline points located on the coast's low-water line (-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 coastlines where we do not have straight baselines. The points on the low-water mark are located on normal baselines and have been selected where the situation is expected to affect the calculation of the territorial boundary of the sea. Low-water inserts are located outside the baselines and have been selected on the corresponding bases. The following attributes can be found in the point shape file: Serial number_dels - Serial number of the baseline points (BP) for the respective leg. Sub-distance — The baselines are presented with the following sub-distances: Mainland and Öland, Gotland including Fårö and Lilla Karlsö, Gotska Sandön, Stora Karlsö, Märket, Märkeshällarna. Point number_name - Numbers and names of baseline points and low tide creeks Latitude & Longitude - All points along the boundary are described by geographical coordinates in latitude and longitude expressed in the SWEREF 99 reference system in degrees and decimal minutes as stated in the law and in decimal degrees. Point type - The following point types exist: • point on the low-water line along the normal baseline (LP), • end point on the straight baseline, baseline point (BP), • segmented point on a straight geodetic line between two baseline points (MP), and • point on low-water core located outside a baseline (LS). Type of baseline - What type of baseline (right/normal) starts at the point. Source - Act (2017:1272) on Sweden's territorial waters and maritime zones. Unique ID – A unique ID added by the Swedish Maritime Administration. The following attributes are in the line shape file: Sub-distance — Straight baseline sub-distance.
