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 map has been produced as a GeoPDF, which is an extension to the standard PDF file format viewed using Adobe Acrobat Reader. Layers can be turned off and on to customise the view of the data, similar to using Geographic Information System tools. In addition, GeoPDF maps are georeferenced to be compatible with other coordinated geographic data. Coordinate locations and distances can be retrieved automatically. A plug-in to view GeoPDF using Adobe Acrobat Reader is available as a free download ( http://terragotech.com/solutions/map2pdf_reader.php ).

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.

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.

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 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.

The Christmas Island Geographic Information System (CIGIS) is a collection of spatial data, viewing and analysis tools dealing with Christmas Island. The data include orthophotography, topographic, mining, cultural and environmental features of the island. 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.

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 railways that link urban and regional Australia have played a significant role in the development of our nation. Rail transport contributes many billions of dollars every year to Australia`s economy. Many of the products we use every day have travelled by rail at some stage in their journey. From home to work or across the country, passenger trains carry more than 500 million people each year - that`s around 25 times Australia`s population! With the opening of the Alice Springs to Darwin line in February 2004, all mainland capital cities and their ports are now connected by a 9420 kilometre network of standard gauge track, known as the Interstate Rail Network. The Railways of Australia thematic map reflects Australia`s impressive rail network. Whether it is used as a functional reference map or simply an outstanding wall-piece, Railways of Australia is a must for all rail enthusiasts and industries that rely on the nation`s rail network. Railways of Australia shows major passenger and freight lines, selected tourist railways, and metropolitan rail networks. Travelling times and distances, length of track, passenger loads, freight tonnage, and fabulous facts about Australia`s rail network are also included. This map was produced with the help of the Australasian Railway Association and Railpage.
