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的核心职责。此项工作的产出之一为澳大利亚海洋边界（Australian Maritime Boundaries，简称AMB）数据集。AMB是一款地理信息系统（Geographic Information System，简称GIS）数据产品，替代了2014版澳大利亚海洋边界（AMB2014a），用于提供澳大利亚海洋海域的数据访问服务。

AMB以数字化形式呈现澳大利亚依据《1973年海洋与大陆架法》（Seas and Submerged Lands Act 1973）及相关公告确立的疆界范围。本数据集同时涵盖依据《2006年近海石油与温室气体储存法》（Offshore Petroleum and Greenhouse Gas Storage Act 2006，简称OPGGSA）划定的澳大利亚各州及北领地的计划海域与近海区域的边界范围。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澳大利亚联邦政府其他相关机构编制发布，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、各海洋海域的外部边界，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。数据集的海岸线位置基于生产时可获取的源资料限定范围确定。用户可通过澳大利亚海洋空间信息系统（AMSIS，http://www.ga.gov.au/marine/jurisdiction/amsis.html）在线查看AMB数据。

AMB数据集的覆盖范围为澳大利亚全部海洋管辖海域，包括毗邻大陆的水域、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。

本数据集附带以下免责声明：
AMB数据是对领海基线及澳大利亚海洋海域外部边界的数字化呈现。上述基线与海域范围依据《1973年海洋与大陆架法》确立。本数据集同时涵盖依据《1980年沿海水域（州权力）法》（Coastal Waters (State Powers) Act 1980）、《1980年沿海水域（北领地权力）法》（Coastal Waters (Northern Territory Powers) Act 1980）及《2006年近海石油与温室气体储存法》划定的澳大利亚各州及北领地毗邻水域的边界范围。若AMB数据集与相关立法规定的基线及边界存在不一致，以立法规定为准。
