The 6th Generation seismic hazard model of Canada is being developed to generate seismic design values for the 2020 National Building Code of Canada (NBCC2020). Ground-motion models (GMMs) from the Next Generation Attenuation (NGA)-West 2 and NGA-East programs are used and epistemic uncertainty in ground-motion models is captured through the use of a classical weighted logic tree framework. For the first time, seismic hazard is computed directly on primary (e.g. A-E) seismic site classes from their time-averaged shear wave velocities in the upper 30 m of the crust (VS30). This approach simplifies the way end users will determine seismic design values for a given location and site class, while having other technical advantages such as capturing epistemic uncertainty in site amplification models. It will remove the need for separate site amplification look-up tables in the building code, enabling users to simply supply their location and site class to determine seismic design values. In general, the new ground- motion models predict higher hazard in most Canadian localities due to a variable combination of changes in median ground motions, site amplification and aleatory uncertainty.

This dataset is a croped version of Population Centres (Geomet 2389). Population centres such as major centres (associated with political DCW dataset (polys) for built up areas), populated places and villages (dataset derived from the Digital Chart of the World (DCW)). For more information on the Digital Chart of the World data please browse the DCW Internet Site http://www.maproom.psu.edu/dcw/. The primary source for DCW is the US Defense Mapping Agency (DMA) Operational Navigation Chart (ONC) series produced by the United States, Australia, Canada, and the United Kingdom. The ONC`s have a scale of 1:1,000,000, where 1 inch equals approximately 16 miles.The charts were designed to meet the needs of pilots and air crews in medium and low altitude en route navigation and to support military operational planning, intelligence briefings, and other needs. Therefore, the selection of ground features is based on the requirement for rapid visual recognition of significant details seen from a low perspective angle. The DCW database was originally published in 1992. Data currency varies from place to place depending on the currency of the ONC charts. Chart currency ranges from the mid 1960`s to the early 1990`s. Compilation dates for every ONC chart are included in the database.

A GIS data set created from a map, first published by BMR in 1983, that depicts the distribution of metamorphic facies in Australia. The original map was compiled between 1972 and 1983 by T.G. Vallance, G.W. DAddario, A.J. Stewart, J.E. Mitchell, J.F. Stirzaker, and A.S.Mikolajczak using data supplied by BMR, State and Territory Geological Surveys, Universities and the Geological Society of Australia. As a digital data set the attributes have been revised to allow relational analysis of the data within. Two formats of GIS data are provided: ArcView shape files and Mapinfo TAB files.

This series covers the whole of Australia at a scale of 1:250,000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. Some maps are supplemented by relief shading. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD Projection: Universal Traverse Mercator (UTM) Medium: Web and DVD Forward Program: Selected maps under revision Topographic geoMAP 250K maps are available free online via Geoscience Australia Interactive Maps service.

The National Groundwater Information System(NGIS), produced by BoM (Bureau of Meterology), is a geodatabase for storing nationally consistent groundwater data based on the ArcHydro for Groundwater data model. Contents include: - bores - bore logs - construction logs - lithology logs - hydrogeologic units - 3D bore lines - 3D construction lines - 3D georasters - 3D geovolumes Data has been provided by the following agencies: NSW Office of Water 03/08/2012 VIC Department of Sustainability and Environment 29/06/2012 SA Department of Environment, Water and Natural Resources 09/11/2012 QLD Department of Natural Resources and Mines 29/08/2012 WA Department of Water 17/02/2012 WA Water Corporation 17/07/2012 TAS Department of Primary Industries, Parks, Water and Environment 06/08/2012 NT Department of Lands, Planning and the Environment 13/08/2012 Data has been exported from corporated state/territory groundwater databases into the NGIS data model. NGIS datawent through the Bureau's NGIS QA/QC process in January - February 2013and were then ingested into the national NGIS geodatabase. The Bureau QA/QC process identified several types of issues from original data stored the state/territory groundwater databases and could not be addressed: Attributes that have not been populated e.g. DrilledDepth, BoreDepth, DrilledDate Attributes with unreasonable values e.g. very large or small values for DrilledDepth and BoreDepth, dates in the future or distant past for DrilledDate

The Australian Maritime Boundaries Web Service is a web based interactive mapping and decision support system that improves access to integrated government and non-government information in the Australian Marine Jurisdiction. The Australian Maritime Boundaries Web Service contains many layers of information displayed in themes of Maritime Boundaries. The data has been sourced from Geoscience Australia, other Australian government agencies and some industry sources. Information in this application should not be relied upon as the sole source of information for commercial and operational decisions. The Australian Maritime Boundaries Web Service should not be used for navigational purposes.
