Seas and Submerged Lands Act 1973 - Australian Maritime Boundaries 2014a - Geodatabase (Geoscience Australia)

Brief description

The dataset depicts the proclamations made under the Seas and Submerged Lands Act (SSLA) 1973. This includes the continental shelf, the Exclusive Economic Zone (EEZ), territorial sea and territorial sea baselines. NOTE: Two versions of the Exclusive Economic Zone (EEZ) are supplied to account for the discrepancy between Seas and Submerged Lands Act 1973, the Proclamation under section 10B (26/07/1994), and unratified Treaty between the Government of Australia and the Government of the Republic of Indonesia, establishing an Exclusive Economic Zone Boundary and Certain Seabed Boundaries (Perth, 14 march 1997) [1997] ATNIF 9 - (not yet in force). Although the proclamation remains in force, for many matters the limit modified by the action of the treaty is the limit that should be applied. This is the default depiction of Australia's EEZ. Geoscience Australia has the primary role in the delineation of Australia's domestic and international maritime limits and boundaries. An output of this activity is the development of the Australian Maritime Boundaries (AMB) data. Note: This is a non authoritative copy of the metadata for the use in the eAtlas. Please refer to Geoscience Australia for queries on this dataset. AMB is a GIS data product, replacing Australian Maritime Boundaries 2014 (AMB2014), providing access to the data for Australia's maritime zones. AMB is a digital representation of Australia's limits and boundaries as established under the Seas and Submerged Lands Act 1973 and associated proclamations. The data also include a representation of the limits by which the scheduled and offshore areas of each of the States and of the Northern Territory are determined under the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGSA). In the event of an inconsistency between AMB data and the limits under any legislation, the latter prevails. The data have been published by Geoscience Australia in consultation with other relevant Commonwealth Government agencies including the Attorney-General's Department, the Department of Foreign Affairs and Trade and the Australian Hydrographic Office. This version contains a number of technical amendments made on the basis of user feedback. These include: Harmonisation of maritime boundaries, scheduled area and graticular block datasets in block SC51 AMB data comprise the territorial straight baselines and the outer limits of each zone, together with maritime boundaries determined by treaties between Australia and neighbouring countries. All data coordinates are supplied in the GDA94 datum. The data reflects the location of the coastline within the constraints of available source material at the time of production. AMB Data can also be viewed on-line via AMSIS (http://www.ga.gov.au/marine/jurisdiction/amsis.html). Product Specifications Coverage: Australia including all external territories Currency: May 2014. Coordinates: Geographical Datum: GDA94 (functionally equivalent to WGS84). Format: ESRI Geodatabase and REST web service - free online. The area of coverage of the AMB data is for the whole of the Australian marine jurisdiction which includes waters adjacent to the mainland, offshore islands and External Territories. The geographical extent is approximately between the latitude limits of 7 S to 70 S and the longitude limits 40 E to 175 E. This dataset includes the following disclaimer: AMB data is a digital representation of the territorial sea baseline and of the outer limits of Australia's maritime zones. The baseline and zones are established under the Seas and Submerged Lands Act 1973. The data also includes a representation of the limits by which the waters adjacent to each of the Australian States and of the Northern Territory are determined under the Coastal Waters (State Powers) Act 1980, Coastal Waters (Northern Territory Powers) Act 1980 and the Offshore Petroleum and Greenhouse Gas Storage Act 2006. In the event of an inconsistency between AMB data and the baselines and limits under the legislation, the latter prevails. eAtlas processing: 1. The original Geodatabase was downloaded from http://dx.doi.org/10.4225/25/5539DFE87D895 on 16 Aug 2019. 2. Each layer in the geodatabase was loaded into ArcMap 10.6 then exported to a Shapefile.

Lineage

The AMB3 dataset is the third iteration of the Australian Maritime Boundary dataset, a dataset designed to provide advice on the limits of Australian maritime jurisdiction. This version is designed differently from the previous two, with a focus on ease of maintenance, a modular concept, fewer but more pertinent attributes, and suitability for an automated system. Additionally, this will be the first version of AMB to be released in GML format. The AMB dataset consists of a series of points, lines and polygons calculated rigorously from a baseline. Whilst visually unimpressive, a considerable amount of work is required to produce these lines. AMB3 aims to provide an improved product to users, and at the same time reduce the overhead needed to maintain the database.
