This service has been created specifically for display in the National Map and the chosen symbology may not suit other mapping applications. The Australian Topographic web map service is seamless national dataset coverage for the whole of Australia. These data are best suited to graphical applications. These data may vary greatly in quality depending on the method of capture and digitising specifications in place at the time of capture. The web map service portrays detailed graphic representation of features that appear on the Earth's surface. These features include the administration boundaries from the Geoscience Australia 250K Topographic Data, including state forest and reserves.

Diagram showing Australia's maritime jurisdiction in the Timor Sea around the JPDA area. An update to an existing map, MP2004/6133, as requested by DFAT to place on their website. Background bathymetric image is derived from a combination of the 2009 9 arc second bathymetric and topographic grid by GA and a grid by Smith and Sandwell, 1997. Background land imagery derived from Blue Marble, NASA's Earth Observatory.

Three maps have been created for RET to include in a Ministerial Briefing on changes to act relating to the area of opperation of NOPSEMA Relates to Advice Register Number 705 Not for public release. RET internal use only.

Australia - Offshore Minerals Act 1994 - Mineral Blocks epoch 2014a. This service displays the Australian Mineral Blocks - Aligned with the current Australian Maritime Boundary Dataset. Refer to the metadata of the geodatabase for a detailed abstract relating to the data.

Map showing Australia's Maritime Jurisdiction off the Northwest Shelf. Updated in June 2014 from "Australia's Maritime Jurisdiction off the Northwest Shelf" (GeoCat 69341) to conform with "Australian Maritime Boundaries 2014" data by Geoscience Australia. One of the 27 constituent maps of the "Australia's Maritime Jurisdiction Map Series" (GeoCat 71789). Depicting Australia's continental shelf as proclaimed in the "Seas and Submerged Lands (Limits of Continental Shelf) Proclamation 2012" established under the "Seas and Submerged Lands Act 1973". Background bathymetric image is derived from a combination of the 2009 9 arc second bathymetric and topographic grid by GA and a grid by Smith and Sandwell, 1997. Background land imagery derived from Blue Marble, NASA's Earth Observatory. A0 sized .pdf downloadable from the web.

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.

Australian Mineral Blocks (2020) - Aligned with the current Australian Maritime Boundary Dataset (AMB2020). ESRI Geodatabase. Available for download as GDA94 or GDA2020. 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 2020 (AMB2020). The 2020 release has been updated to reflect the 2018 Timor Sea Treaty. 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.

Map showing Australia's Maritime Jurisdiction around the Australian Continent, not including Cocos Island, subantarctic territories or the AAT. Updated in June 2014 from "Australia's Maritime Jurisdiction around Australia" GeoCat 69122 to conform with "Australian Maritime Boundaries 2014" data by Geoscience Australia. One of the 27 constituent maps of the "Australia's Maritime Jurisdiction Map Series" (GeoCat 71789). Depicting Australia's continental shelf as proclaimed in the "Seas and Submerged Lands (Limits of Continental Shelf) Proclamation 2012" established under the "Seas and Submerged Lands Act 1973".

The dataset was created by Geoscience Australia using the framework described in Section 33 of the Offshore Minerals Act 1994. The international, scheduled areas and coastal waters used in this dataset are those found in the historical Australian Maritime Boundary Dataset 2006 (AMB2006). 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 AMB2006 -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%.
