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 historical Australian Maritime Boundary Dataset 2006 (AMB2006). 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 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. Existing production licences AC/P17, AC/RL4, and AC/RL5 are included in the dataset. The blocks are attributed with fields containing information on: - Parent 1 Million Mapsheet - Offshore Area - Epoch of the boundaries used to cut the data AMB2001 - 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 OPGGS Act, the area of a block has no relevance. Therefore the area figure is provided solely for reference.

The Gazetteer provides information on the location and spelling of more than 332 000 geographical names across Australia as at January 2011. The supply of data is coordinated by the Intergovernmental Committee on Surveying and Mapping and derived from State, Territory and Australian Government agencies. Copyright of the Gazetteer data resides with the relevant state, territory and Australian Government agencies which are custodians of the data. The Gazetteer fields include: - Record ID - unique feature identifier for each feature. - Authority ID - custodian state or territory. - State ID - state or territory which contains the feature. - Name - name of the feature. - Feature Code - code indicating the type of feature - Status - indicates whether the name is authorised. - Variant name - variant or alternative name used for the feature. - Postcode - Postcode for the feature. - Concise Gazetteer - indicates whether the feature is included in the concise gazetteer. - Longitude - longitude of the feature in decimal degrees. - Latitude - latitude of the feature in decimal degrees. - 100K map number - 1:100 000 scale map number in which the feature is located. - CGDN - indicates whether the place name can be used in the state.au second level domains by community website portals which reflect community interests. Product specifications: - Coverage: Australia - Currency: 2010 - Coordinates: Geographical - Datum: GDA94 - Format: Fixed width ASCII and Microsoft Access Database - Medium: WEB - Forward Program: Annual revision Please note: The custodians of the place name data do not guarantee that the data is free from errors and omissions. If possible errors or omissions in the data are identified, please contact <a href=mailto:gazetteer@ga.gov.au>gazetteer@ga.gov.au</a>, corrections are forwarded to the State and Territories, Name Authorities for clarification. Updates will appear in subsequent revisions of the Gazetteer.
