These pages comprise the National Geoscience Datasets Internet Facility which delivers AGSO clients online access to AGSO's National scale spatial geoscience information. AGSO has responsibility for the production and online access to primary geoscience information of relevance to resource issues for industry, government and the general public, provided in the form of digital datasets that cover the Australian continent and/or Australian marine jurisdictional areas. This facility will provide efficient, modern digital-era access to all the geoscience information available in current maps and associated digital databases at the best possible resolution. To add to this as new geoscience datasets are released they will become available on the National Geoscience Datasets download page and be viewable within the National datasets online GIS web mapping tool.

The integrated spatial database of geological, geophysical, geochemical and cultural data. Provides users with means of integrating and analysing data for mineral exploration and research. The area covered by GIS encompasses Broken Hill and Euriowie Blocks and comprises six 1:100 000 mapsheets; the Corona, Fowlers Gap, Broken Hill, Taltingan, Redan and Thackaringa.

The South Australia Geoscientific Geographic Information System is a state wide integration of geological, geophysical, geochemical and cultural data. It provides the Geological Survey, Minerals & Energy Division, PIRSA, with its primary mechanism for distributing regional geoscientific information for exploration and research, via digital media. Datasets in this package are projected in Universal Transverse Mercator (UTM) Map Grid of Australia (MGA) coordinates relative to GDA94. The datasets are split into the three grid zones 52, 53 and 54, which span South Australia.

The Northern Australian Project online GIS, which has been chiefly designed to highlight the results of geochronological research within the project area, was first published in 2003 and updated in July 2004. GIS data reference layers include 1: 250,000, 1: 1 million, and 1: 2,500,000 geological data, regional geophysical images and a topographic map image. The geochronology and fluid inclusion points have been linked live to Geoscience Australia's OZROCKS, OZCHRON and PETROG Oracle databases. Forms display data to the user from these databases using customised query statements. Queries directed to geological layers display information derived from static ArcInfo shapefiles. The North Australia Project geochronology research has chiefly targeted the Arunta Block, Davenport Geosyncline, and the Granites-Tanami Block provinces within the project area.

This dataset delineates political areas such as built up areas, land, ocean, pack ice and boundaries such as coastlines, city limits etc. (dataset derived from the Digital Chart of the World (DCW). Generic information on DCW data sets 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 ONCs 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 1960s to the early 1990s. Compilation dates for every ONC chart are included in the database. For more information on the Digital Chart of the World please browse the DCW website where you can download these data in VPF format. GA has converted these VPF format files to common GIS formats Arcview and Mapinfo. Available datasets include drainage, roads and railway networks, political areas and boundaries and population centres. Available for free download.

Population centres such as major centres (associated with political Digital Chart of the World (DCW) dataset (polys) for built up areas), populated places and villages (dataset derived from the Digital Chart of the World).

An integrated package comprising geological, structural, geophysical, geochronological and geochemical data. The GIS encompasses the outcropping and covered portions of Palaeoproterozoic and Mesoproterozoic rocks straddling the NSW-SA border (the Broken Hill, Euriowie, Olary, Mount Painter and Mount Babbage Inliers). The GIS features recent data collected by the Broken Hill Exploration Initiative.

The Nauru GIS was created for both broad scale and detailed planning of rehabilitation and secondary mining. However, it also contains other datasets (e.g buildings, roads, storage tanks etc) which although are not error free may be of interest and prove useful for other purposes. The primary components for this product were to provide: ? geocorrected images (Orthophotography), ? Digital Elevation Models, ? data integration and system development ? training. This product was designed and compiled by the Australian Geological Survey Organisation on behalf of the Nauru Rehabilitation Corporation and the Nauru Phosphate Corporation, Republic of Nauru. The project commeced in November 1999, following a scoping report written in March 1999 and was completed by June 2000. This product is referred to as the Level 1 ArcExplorer GIS as described in the Scoping and Progress Reports and the final system documentation.

The Cocos (Keeling) Islands Geographic Information System (CocosGIS) is a collection of spatial data, viewing and analysis tools dealing with the Cocos (Keeling) Islands. The data include orthophotography, topographic, cultural and environmental features both of the islands and the ocean immediately surrounding them. Compilation of data and its organisation into a GIS together with documentation was undertaken by the Australian Geological Survey Organisation (AGSO) at the request of the Territories Office, Department of Transport and Regional Services (DOTRS). The data are presented in both ESRI ArcView and ArcExplorer projects. The ArcView projects require a licensed copy of ArcView. ArcExplorer is a free viewer and is distributed with the Cocos GIS CD-ROM. Data are stored as ESRI shapefiles and therefore readily useable with most modern GIS applications. Data were received from a variety of custodians and in many cases had no accompanying documentation. Lack of documentation made it increasingly difficult for AGSO with interpretation, translation and documentation of data. AGSO has attempted to include metadata for all datasets to ANZLIC core metadata standards, but the value of this is limited by the poor initial documentation. In addition to limited documentation, many datasets had inconsistent spatial accuracy. The CocosGIS comprises four main CD-ROMs with additional CD-ROMs containing full-colour orthophotography. A hard-copy user guide is distributed with the main CD-ROM set.

These datasets are compiled from a mosaic of NMD`s TOPO250K data product for the transport datasets (rail, roads and airfields) and drainage datasets (alig5md and alig250d). The population centres datasets (alig25mc and alig250mp) are derived from NMD`s mosaiced localities dataset. alig25mp is a subset based on the attribute location for populated places only. The alig25mc is a subset containing the capital cities and selected regional centres. The alig5md is the 1:5,000,000 scale drainage network which includes lakes (alig5ml). These AUSLIG datasets are much more accurate than the DCW datasets and have more attributes. More information on the AUSLIG 250K datasets can be found in the Overview.txt file in /d/geo/store/data/topo/geodata/topo~250k/aus_mosaic. NOTE : THERE ARE NO ARCINFO DATASETS stored in the arcinfo/culture/auslig directory only shapefiles held in arcview/culture/auslig. The reason for this is the original arcinfo datasets are available from the data store at /d/geo/store/data/topo/geodata/topo~250k/aus_mosaic.
