The Australian Marine Spatial Information System (AMSIS) is a web based interactive mapping and decision support system that improves access to integrated government and non-government information in the Australian Marine Jurisdiction. AMSIS is a decision support tool maintained by Geoscience Australia that brings together information required by Government, industry and private individuals with an interest in the regulation, geography and uses of Australia’s Marine Jurisdiction. AMSIS provides a mechanism to visualise competing interests in the marine space; using curated data from across Government, State, and academia to expose competing use, and enable discussion with the multi-sectoral users to better plan and manage the Jurisdiction. AMSIS contains many layers of information displayed in themes of Australia’s Maritime Boundaries, Petroleum, Fisheries, Environment, Native Title and general Regulation. Geoscience Australia is working with other Australian Government agencies, Industry and Academia to add additional information that will improve the functionality of AMSIS. All information provided in AMSIS is the best available at the time of publication. Although the best efforts have been made to ensure the information is current and accurate, the information is not warranted to be correct. Users should investigate the metadata records to understand the limitations on any information layer, and consult with the regulating agency before making any decision.

Offshore Minerals Act (OMA 1994) - Mineral Blocks. This service displays the most recent realisation of the Mineral Blocks as defined under the Offshore Minerals Act 1994 (OMA 1994) as realised in GDA94. Block data extends beyond the area of operation of the OMA and includes areas of coastal waters and land within the constitutional limits of the States and Territories.

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 AMBIS 2006, providing access to the data for Australia's maritime zones. Treaties - Australian Maritime Boundaries Dataset 2014 is a digital representation of Australia's international treaty boundaries. In the event of an inconsistency between AMB data and the limits under any treaty, 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 The Treaties - Australian Maritime Boundaries Dataset 2014a comprises the maritime boundaries determined by treaties between Australia and neighbouring countries. All data coordinates are supplied in the GDA94 datum. Treaties - Australian Maritime Boundaries Dataset 2014a can also be viewed on-line via AMSIS (http://www.ga.gov.au/marine/jurisdiction/amsis.html).

AMSIS is a web based interactive mapping and decision support system that improves access to integrated government and non-government information in the Australian Marine Jurisdiction. AMSIS contains over 80 layers of information including maritime boundaries, bathymetry, physical and environmental information, legal interests, fisheries and shipping that has been sourced from Geoscience Australia, other Australian government agencies and some industry sources. AMSIS also contains the offshore mineral locations data that was used to create the Offshore Minerals Map. AMSIS has been developed using standards to support interoperability enabling integration with the National Oceans Portal and other on-line initiatives. Geoscience Australia is working with other agencies and organisations to add additional information. Information in this application should not be relied upon as the sole source of information for commercial and operational decisions. AMSIS should not be used for navigational purposes.

Australian Mineral Blocks (2014) - Aligned with the current Australian Maritime Boundary Dataset (AMB2014). ESRI Geodatabase. The dataset was created by Geoscience Australia using the framework described in Section 17 of the Offshore Minerals Act 1994. The international, scheduled areas and coastal waters used in this dataset are those found in the current Australian Maritime Boundary Dataset 2014 (AMB2014). The dataset is comprised of both polygons and points created to very high precision, accurate to within millimetres. The blocks have been cut by Australia's international boundaries, the scheduled areas and the coastal waters. Each block is assigned a polygon, including partial blocks. All blocks are titled with their block ID, and a list of vertices that make up the blocks. Each vertex of the dataset is also replicated as a discrete point in the points dataset. The design of the dataset allows for the exact location of every vertex to be known to millimetre precision. The corner coordinates of blocks are now defined to a high precision, and can be found by querying the appropriate point. The blocks are attributed with fields containing information on: Block ID Parent 1 Million Mapsheet Offshore Area Epoch of the boundaries used to cut the data AMB2014 Datum Origin of the mapsheet in AGD66 The position of all vertices in the block The number of vertices in the block The area of the block in acres The area of the block in hectares The calculation used to find the area of the blocks is estimated to be precise to better than 1%. This is considered to be sufficient as under the permit and licensing arrangements in the Offshore Minerals Act, the area of a block has no relevance. Therefore the area figure is provided solely for reference.

The dataset was created by Geoscience Australia using the framework described in Section 33 of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGS Act) and previous Acts. The international, scheduled areas and coastal waters used in this dataset are those found in the current Australian Maritime Boundary Dataset 2014 (AMB2014a). This version contains a number of technical amendments made on the basis of user feedback. These include: - Removal of lease AC/P17 - Harmonisation of maritime boundaries, scheduled area and graticular block datasets in block SC51 The dataset is comprised of both polygons and points created to very high precision, accurate to within millimetres.

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.

Geoscience Australia is responsible for the definition of Australia's maritime boundaries. To assist in this task National Mapping has developed the Australian Maritime Boundaries Information System (AMBIS). AMBIS 2001 is a data product, derived from AMBIS, providing access to the data for Australia's Territorial Sea Baseline (TSB) and maritime zones. AMBIS 2001 data comprises the TSB and the outer limits of each zone, together with quality attributes. Base points that generate the zone boundaries are supplied in separate files and an extensive user guide provides useful background information. All data coordinates are supplied in the Geocentric Datum of Australia (GDA 94) which is effectively identical to the WGS84 datum. National Mapping is committed to the maintenance of the AMBIS data to ensure it reflects the changing nature of Australia's coastline and hence the various maritime zone limits. To this effect, a newly revised AMBIS 2001 product (version 1.1) has been released in October 2001. This new version incorporates additional treaty information, additional data in the vicinity of Swains Reef in Queensland, an improved representation of the TSB, several other minor corrections, a wider range of formats and simplified attribute tables.
