Scientists within Geoscience Australia (GA) create complex 3D models of geological structures, using specialised 3D modelling software. Very few people outside of GA have access to this specialised software. To provide clients and stakeholders with access to 3D information GA has developed VRML-HTML-JavaScript interfaces. These interfaces allow GA to share large volumes of complex 3D geological information via the Web, with data volumes up to 22 MB. A number of methods are employed to allow users to interact with such large amounts of data. The geometric features within VRML are used to represent a wide range of geological features. The interfaces are user friendly and provide users with a high level of interaction with the complex information.

X3D Earth is a planned virtual globe application from the Web3D Consortium. It will differ from Google Earth (GE) (and other existing virtual globes) in the following ways: it will use an existing open source standard 3D file format (X3D); be truly 3D (most other virtual globes do not currently handle sub-surface data); allow distributed storage of the 3D data; and allow agencies such as GA to create and distribute their own data. One motivation for developing X3D Earth is to provide a mechanism for long term and open access to public 3D geospatial data. Development is planned for 2006/07. This whitepaper is Geoscience Australia's contribution to the X3D Earth requirements workshop, November 2006.

This Professional Opinion reports the interim findings of a consultancy undertaken for the Secretariat for the Pacific Regional Environment Programme (SPREP) by Geoscience Australia in the period 15 December 2010 to 2 April 2011. Geoscience Australia was engaged by SPREP to assist in developing a business case for a Pacific Climate Change Portal. This portal will act as a focus for climate and climate change information relevant to the Pacific, provide up to date information for decision makers, and researchers, and improve communication and collaboration in adaptation initiatives by national, regional and international stakeholders. Geoscience Australia has consulted as much as possible in the time available with stakeholders for the portal identified by SPREP to be 'core'. These stakeholders include the Secretariat of the Pacific Community (SPC), United Nations organisations, notably the United Nations Development Programme (UNDP), and the National Oceanographic and Atmospheric Administration (NOAA), along with SPREP itself. The consultations allowed Geoscience Australia to identify key issues, recommend core functionalities of the portal and a preferred operational model and identify partnerships and resources required for sustainable, long term operation of the portal. As a part of this consultancy, Geoscience Australia constructed a 'demonstrator' Pacific Climate Change web portal to illustrate how users could operate the proposed key functionalities of the portal, and to give potential users an illustration of two 'look and feel' options. This demonstrator portal can be visited at http://www.pacificportal.com.au/ . It will be active until approximately the end of June 2011.

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 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 vegetation theme from the Geoscience Australia 250K Topographic Data. The service contains layer scale dependencies.

This web service provides access to the National Liquid Fuel Facilities Datasets, representing the spatial locations of all known liquid fuel depots, refineries, terminals and petrol stations located within Australia, all complemented with feature attribution.

This web service provides access to the National Foreign Embassies and Consulates Datasets, representing the spatial locations of all known foreign embassies, high commissions and consulates located within Australia, all complemented with feature attribution.

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.

This web service provides access to the National Dam Walls dataset and presents the spatial locations of major dam walls located within Australia, all complemented with feature attribution.

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.
