Due to licence restrictions on the National Electricity Transmission Substations dataset, the metadata statement is the only information available for release. For further information contact clientservices@ga.gov.au The dataset held by GA contains the spatial locations for Electricity Transmission Substations in Australia in point format as a representation of the substation features.

The National Major Dam Walls dataset presents the spatial locations; in point and polygon format, of all known major dam walls within Australia.

This point dataset contains the Australian Coastal Maritime Navigation Aids including 'traditional-type' lighthouses and the newer solar powered automated lights.

The National Wastewater Treatment Facilities Database presents the spatial locations of Australia's known wastewater treatment plants. The purpose of the National Wastewater Treatment Plants Database is to support decision makers from industry, governments and other interested parties make better, and more informed decisions based on evidence based information.

This point dataset contains the major airport fuel storage and supply facilities in Australia.

The dataset contains spatial locations, in point format, of the Australian High Court, Australian Federal Courts and the Australian Magistrates Courts.

The dataset contains spatial locations in point format as a representation of Immigration Detention Facilities in Australia. Definition: Immigration detention centres primarily accommodate people who have overstayed their visa, breached their visa conditions and had their visa cancelled or have been refused entry at Australia's entry ports.

The datasets contain spatial locations in point format as a representation of embassies, high commissions and consulate facilities/missions in Australia.

The Greater Metro Manila Area is one of the world's megacities and is home to about 12 million people. It is located in a region at risk from earthquakes, volcanic eruptions, tropical cyclones, riverine flooding, landslides and other natural hazards. Major flooding affected the Greater Metro Manila Area in September 2009 following the passage of Typhoon Ketsana (known locally as Typhoon Ondoy). Following this event, the Australian Aid Program supported Geoscience Australia to undertake a capacity building project with its partner agencies in the Government of the Philippines. The output of this project has been a series of risk information products developed by agencies in the Collective Strengthening of Community Awareness for Natural Disasters (CSCAND) group. These products quantify the expected physical damage and economic loss to buildings caused by earthquakes, tropical cyclone severe wind and riverine flooding across the Greater Metro Manila Area. Spatial data is a key input to the development of hazard models and information on exposure, or the 'elements at risk'. The development of a spatially enabled exposure database was a crucial element in the construction of risk information products for the Greater Metro Manila Area. The database provides one central repository to host consistent information about the location, size, type, age, residential population and structural characteristics of buildings within the area of interest. Unique spatial analysis techniques were employed to quantify and record important aspects of the built environment, for inclusion in the database. The process of exposure data development within the Greater Metro Manila Area, including a new application developed by Geoscience Australia for estimating the geometric characteristics of buildings from high resolution elevation data and multi-spectral imagery, will be presented.

Governments at the Commonwealth, State, Territory and Local level are committed to minimising the impact of natural disasters through a variety of Disaster Risk Reduction (DRR) programs. Risk analysis is one of the processes undertaken to inform DRR decision making and policy development. It involves estimating the extent and severity of one or more natural hazards, understanding the location and characteristics of the 'elements at risk' from those hazards (also known as exposure) and modelling the vulnerability and response of those elements exposed to the subject hazards. Understanding the vulnerability of buildings is crucial in risk analysis activities, as damage to buildings can have significant direct and indirect impacts on individuals, communities, economies and the functioning of society at large. The development of quality spatially-enabled information is a key activity in the risk analysis process. After demonstrating a proof of concept in 2005-2006, Geoscience Australia has led the development of exposure information for Australia via the National Exposure Information System (NEXIS). Within NEXIS, currently available spatial and non-spatial data from various sources is routinely combined, reorganised for consistency, managed and supplied to stakeholders. The products derived from NEXIS enable risk analysis specialists and policy makers to access recent exposure information they require to analyse and assess the risk posed by the hazards in Australia. At the core of NEXIS is information about buildings. There are many challenges to developing and providing reliable information about buildings across the country. Through an offer of assistance from the ACT Government, Geoscience Australia has developed an innovative and rapid method to analyse and interpret cadastral data to estimate an important exposure attribute. This presentation describes the development of the method, the resulting benefits for exposure information in the ACT and outlines how cadastral data can improve DRR outcomes across Australia.
