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.

Please note: This product has been superseded by 50m Multibeam Dataset of Australia 2018. - This tile contains all multibeam data held by Geoscience Australia on August 2012 within the specified area. The data has been gridded to 50m resolution. Some deeper data has also been interpolated within the mapped area. The image provided can be viewed on the free software CARIS Easyview, available from the CARIS website: www.caris.com under Free Downloads.

This is a proof of concept web service displaying trial samples of historic flood mapping from satellite. Over the next 2 years this service will be developed into a nationwide portal displaying flooding across Australia as observed by satellite since 1987. The service shows a summary of water observed by the Landsat-5 and MODIS satellites across Australia for periods between 2000 and 2012. The first layer set displays national observed water from MODIS fvrom 2000 to 2012, as derived by Geoscience Australia using an automated flood mapping algorithm. The colouring of the display represents the frequency of observed water in a 500 x 500m grid. The higher the number, the more often water was observed by the satellites over the period. This means that floods have low values, while lakes, dams and other permanent water bodies have high values. The three additional layer sets are study areas demonstrating the water observed in each study area by the Landsat-5 satellite, as derived by Geoscience Australia using an automated flood mapping algorithm. The study areas and the observation periods are: Study Area 1, Condamine River system between Condamine and Chinchilla, Qld, observed between 2006 and 2011 Study Area 2, North-west Victorian rivers between Shepparton and Kerang, observed between 2006 and 2011 Study Area 3, Northern Qld rivers, near Normanton, observed between 2003 and 2011 Each Study Area layer set includes a water summary displaying the frequency of observed water in 25 x 25m grids, plus individual flood extents for specific dates where flooding was observed. Similar to the national, MODIS summary, the higher the value, the more often water was observed by the satellites over the period. Limitations of the Information The automated flood mapping algorithm can confuse cloud shadows and snow with flood water, so some areas shown as water may be incorrect. This is a proof of concept dataset and has not been validated.

OPGGSA 2006 - Petroleum Blocks. This service displays the most recent realisation of the Petroleum Blocks as defined under Section 33 (3) of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGSA 2006) as realised in GDA94. Block data extends beyond the area of operation of the OPGGSA and includes areas of coastal waters and land within the constitutional limits of the States and Territories.

Not current – This service has been deprecated in favor of the 2019 epoch, which includes amendments reflecting new boundary arrangements with Timor-Leste, which came into force on 30 August 2019. The Seas and Submerged Lands Act (SSLA) is the Australian legislation that provides the framework for Australia to declare the baselines, limits and zones provided under the first six parts of the United Nations Convention on the Law of the Sea. These baselines, limits and zones are declared by Proclamations provided for under this act. This service depicts official spatial representation of these proclamations. The service includes feature layers: Normal and Straight baselines limits and locations, Contiguous Zone and limit, Territorial Sea Zone and limit, Exclusive Economic Zone (EEZ) and limit, Continental Shelf limit and locations. NOTE: There are two versions of the Exclusive Economic Zone (EEZ) provided. One depicts the EEZ as proclaimed in the Seas and Submerged Lands Act 1973 - Proclamation under section 10B (26/07/1994). The second version includes amendments reflecting the provisions of the signed but not unratified Treaty between the Government of Australia and the Government of the Republic of Indonesia, establishing an Exclusive Economic Zone Boundary and Certain Seabed Boundaries (Perth, 14 march 1997) [1997] ATNIF 9 - (not yet in force). (Perth Treaty). The version reflecting Perth Treaty EEZ limits and area should be the standard depiction.

Petroleum Blocks cut to the AMB 2014a epoch. The service contains the Blocks as defined under Section 33 (3) of the Offshore Petroleum and Greenhouse Gas Storage Act 2006. Coverage includes indicative areas of coastal waters and land, within the constitutional limits of the States and territories.

The Geomorphic Features of Australia's Marine Jurisdiction web service brings together various datasets produced by Geoscience Australia that describe the distribution and types of geomorphic features found on the seabed of Australia's marine jurisdiction. This jurisdiction covers Australia's Exclusive Economic Zone, including offshore islands and territories. Geomorphic features have been identified using the best available bathymetric data with features generally mapped at a scale of 1:5 000 000.

This web service provides access to the National Local Government Area Council Offices dataset and presents the spatial locations of all known Local Government Area council office facilities within Australia, all complemented with feature attribution.
