Coastal Waters (State/Territory Powers) Act 1980 - Australian Maritime Boundaries 2020 - Geodatabase

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. AMB is a GIS data product, replacing Australian Maritime Boundaries 2014a (AMB2014a), 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.

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: December 2020. 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.

澳大利亚地球科学局（Geoscience Australia）承担划定澳大利亚国内及国际海洋疆界与边界的核心职责。此项工作的一项产出成果为澳大利亚海洋边界（Australian Maritime Boundaries, AMB）数据集。AMB为地理信息系统（GIS）数据产品，替代了《2014年澳大利亚海洋边界》（AMB2014a），可用于获取澳大利亚各海洋管辖区域的相关数据。AMB以数字化形式呈现澳大利亚依据1973年《海洋与海底土地法》及相关公告所确立的疆界与边界。该数据集还包含依据2006年《近海石油与温室气体储存法》（OPGGSA）划定的澳大利亚各州及北领地的指定近海区域边界。若AMB数据集与相关立法规定的疆界存在不一致，以立法规定为准。该数据集由澳大利亚地球科学局联合其他相关联邦政府机构编制发布，包括总检察长部、外交与贸易部以及澳大利亚水文局。

AMB数据集包含领海直线基线、各海洋区域的外边界，以及澳大利亚与邻国通过条约划定的海洋边界。所有数据坐标均采用GDA94基准面。数据集反映了编制当期可获取的源材料约束下的海岸线位置。用户可通过澳大利亚海洋与海事空间信息系统（AMSIS，http://www.ga.gov.au/marine/jurisdiction/amsis.html）在线查看AMB数据。

产品规格：
覆盖范围：澳大利亚全境及所有海外领地
更新时间：2020年12月
坐标系统：地理基准面为GDA94（功能上等同于世界大地测量系统1984（WGS84））
数据格式：ESRI地理数据库与REST网络服务，可免费在线获取

AMB数据集的覆盖范围为澳大利亚全部海洋管辖区域，包括毗邻大陆的海域、近海岛屿及海外领地。其地理范围大致介于南纬7°至南纬70°，东经40°至东经175°之间。

本数据集包含以下免责声明：
AMB数据为领海基线及澳大利亚各海洋区域外边界的数字化呈现形式。上述基线与区域依据1973年《海洋与海底土地法》确立。数据集还包含依据1980年《沿海水域（州权力）法》、1980年《沿海水域（北领地权力）法》及2006年《近海石油与温室气体储存法》划定的毗邻澳大利亚各州及北领地的水域边界。若AMB数据集与立法规定的基线及边界存在不一致，以立法规定为准。
