Seas and Submerged Lands Act 1973 - Australian Maritime Boundaries 2014a - 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 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.

澳大利亚地球科学局承担划定澳大利亚国内及国际海洋界限与边界的核心职责。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版澳大利亚海洋边界（AMB2014），可用于获取澳大利亚海洋管辖海域的相关数据。AMB是对澳大利亚依据《1973年海洋与海底土地法》及相关公告所确立的界限与边界的数字化呈现。本数据集还包含依据《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预定海域与近海区块边界。若AMB数据集内容与相关立法规定的界限存在不一致，以立法规定为准。本数据集由澳大利亚地球科学局会同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。

本版本纳入了基于用户反馈作出的多项技术修正，其中包括：
· 对SC51区块内的海洋边界、预定海域及格网区块数据集进行协调统一。

AMB数据集包含领海直线基线及各海洋管辖海域的外边界，以及澳大利亚与周边国家通过条约划定的海洋边界。所有数据坐标均采用GDA94大地基准面。本数据集基于生产时可获取的源资料，呈现了海岸线的位置。用户可通过澳大利亚海洋管辖信息系统（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
更新时限：2014年5月
坐标系统：大地基准面为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度至70度，东经40度至175度之间。

本数据集包含如下免责声明：
AMB数据为领海基线及澳大利亚海洋管辖海域外边界的数字化呈现，上述基线与海域均依据《1973年海洋与海底土地法》确立。本数据集还包含依据《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数据集内容与相关立法规定的基线及界限存在不一致，以立法规定为准。
