Baseline - Spatial object type

Definition: The line from which the outer limits of the territorial sea and certain other outer limits are measured.

Description: SOURCE IHO Dictionary, S-32, Fifth Edition.NOTE The baseline comprises of one or more baseline segments.According to United Nations Convention on the Law of the Sea (UNCLOS), the baseline segment can be normal, straight or archipelagic depending on the method used to determine the baseline segment. COMMENT: For this moment there is no clearly identified use-case that would require Baseline spatial object types, therefore it is not strictly necessary to include these objects in the dataset.

Definition: External object identifier of the spatial object.

Description: NOTE An external object identifier is a unique object identifier published by the responsible body, which may be used by external applications to reference the spatial object. The identifier is an identifier of the spatial object, not an identifier of the real-world phenomenon.
