Fire-Note is a 6000+ circulation bulletin of the Aust. Fire and Emergency Service Australia Council (AFAC). This Fire-Note introduces GA's NEXIS (National EXposure Information System) to the fire and emergency services community.

The Australian Geological Survey Organisation (AGSO) presents its solutions to mapping and GIS on the Internet. Software used is based on commercial and open source products. A distributed web mapping system is demonstrated, and concepts of distributed web mapping discussed. Systems for online delivery of spatial data are also demonstrated. AGSO has been providing Internet access to spatial data since 1996. AGSO is the main repository for national geoscientific data, and services a wide range of clients across industry, government and the general public. Data provided range from point data, such as site descriptions and scientific analysis of samples, to line, polygon and grid data, such as geological and geophysical surveys and associated maps. AGSO currently holds 500 MB of GIS data and a similar amount of image data on its web site; these data are expected to expand to a number of terabytes over the next few years. A primary role of AGSO is to provide its data to clients and stakeholders in as efficient a way as possible, hence its choice of Internet delivery. The major obstacle for supplying data of large volume over the Internet is bandwidth. Many AGSO clients are in remote locations with low bandwidth connections to the Internet. Possible solutions to this problem are presented. Examples of AGSO web tools are available at http://www.agso.gov.au/map/

NOTE: removed on request: 25 May 2016 by Sundaram Baskaran GWATER is a corporate database designed to accommodate a number of existing project groundwater and surface water data sets in AGSO. One of the aims in developing the database as a corporate repository is to enable sharing between AGSO projects allowing re-use of data sets derived from various sources such as the State and Territory water authorities. The database would also facilitate an easier exchange of data between AGSO and these authorities. This document presents an overview of the current structure of the database, and describes the present data entry and retrieval forms in some detail. Definitions of all tables and data fields contained within them are listed in an appendix. The database structure will not remain static. Future developments, such as the integration of data directly out of the database into geographic information systems, are expected to lead to modifications in the database structure with possible addition of new tables or fields. Use of GWATER by a range of project areas will undoubtedly lead to different needs in accessing the data, resulting in the request for further development of the data access tools.

Digital technology and the Internet have contributed to the information explosion and in part the widespread increase in the use of spatial information. In this regard community needs for geoscientific information has extended beyond the traditional area of mineral and petroleum exploration. Geoscience is now recognised by society as having a part to play in the achievement of social wellbeing and environmental outcomes. This paper examines whether the geoscience data providers are playing their part in the data explosion. It looks at how geoscience can be applied to real world problems and questions whether the data providers are up to the mark in satisfying the immediate expectations of users as well as initiating new areas of application. The discussion incorporates issues of price, accessibility, formats and data assemblage in relation to a hierarchy of need for decision making.

Over the past 10 years, Australia has maintained 65-85% self-sufficiency in oil and better than 100% suffiency in gas. This has generated significant societal benefits in terms of employment, balance of payments, and revenue. However the decline of the super-giant Gippsland fields, discovery of smaller oil pools on the Northwest Shelf, and the increasing reliance on condensate to sustain our liquids supply sharpens the focus on Australia's need to increase exporation and discover more oil. Australia is competing in the global market place for exploration funds but as it is relatively under-explored there is a need to simulate interest through access to pre-competitive data and information. Public access to exploration and production data is a key plank in Australian promotion of petroleum exploration acreage. Access results from legislation that initially subsidised exploration in return for lodgement and public availability of exploration and production (E&P) data. Today publicly available E&P data ranges from digital seismic tapes, to core and cuttings samples from wells, and access to relational databases, including organic geochemistry, biostratigraphy, and shows information. Seismic information is being progressively consolidated to high density media. Under the Commonwealth Government?s Spatial Information and Data Access Policy, announced in 2001, company data is publicly available at the cost of transfer, after a relatively brief confidentiality period. In addition, pre-competitive regional studies relating to petroleum prospectivity, undertaken by Government, and databases and spatial information is free over the Internet, further reducing the cost of exploration. In cooperation with the Australian States and the Northern Territory, we are working towards jointly presenting Australian opportunities through the Geoscience Portal (http://www.geoscience.gov.au) and a virtual one stop data repository. The challenge now is to translate data availability to increased exploration uptake, through client information, and through ever-improving on-line access.

This was the fifth in the series of successful Forums on geoscience information management that have been held in Canberra since 1993. With the growing use of the Internet for access and delivery of data and services, it was timely to address issues relating to the provision of geoscience online. 2001 will see the implementation of the Federal Government's online policy. AGSO along with state geological agencies will present their online data delivery initiatives. The Forum included a range of speakers dealing with the online delivery of spatial geoscience data, from geoscience-related vendors through to the latest developers in web technology. The geoscience sector is on the cusp of taking full advantage of the potential of online delivery. Over the past 5 years most government agencies have been improving their data management practices and cleaning up their datasets, leading to a situation where the "backend" is in good shape. Some have begun to implement online delivery and eCommerce systems (GIS, image processing and database access) but uptake is uneven across the sector and such systems generally only deliver the lower volume, less commercially sensitive datasets. In the private sector we have begun to see the emergence of commercial data management consultants who are providing web based access to their clients, and, within the larger companies, some sophisticated intrAnet solutions have been put in place. A small number of players are looking at providing online value-added services for clients like share market investors (mining/petroleum shares). This Forum provided the opportunity to find out the latest trends and developments in the exciting and growing area of internet and web technologies for the delivery of online information.

The Australian National Marine Data Group was formed by the Heads of Marine Agencies (HOMA) to promote improved interchange of marine data in Australia. The ANMDG held a workshop of practitioners in May 2002 with the intention of identifying major areas of interest and tasks for working groups to address in order to make progress with development of marine data interchange in Australia. This Proceedings CD contains the presentations by speakers in the form of PowerPoint slides and a few Acrobat documents. It was distributed to participants in the workshop.

The International Forest Carbon Initiative, IFCI, is part of Australia's contribution to international efforts on reducing carbon emissions from deforestation and forest degradation. It focuses on technology transfer to developing countries by assisting them to implement national carbon accounting schemes modelled on that established by the Department of Climate Change and Energy Efficiency. Key inputs to those accounting schemes are mosaics of the best available satellite scenes in a given year. Collections of these mosaics, spanning periods of at least a decade, are used to determine changes to the extent and type of forest cover. Those characterisations are used to determine net forest carbon flux, which is a significant component of overall carbon flows in tropical countries. In support of these activities, Geoscience Australia manages a project to obtain, process, archive and distribute large volumes of satellite data, initially with a focus on Indonesia and other parts of Asia. Three key changes from 'business as usual' activities were required to process and manage, on a large scale, a satellite data time-series to support the International Forest Carbon Initiative. First, at Geoscience Australia, a new facility known as the Earth Observation Data Store is being developed. Secondly, innovative techniques such as the use of USB Flash Drives for data distribution and of DVDs for quick look catalogue distribution have proved beneficial for the participating agencies in developing countries, as well as for data transfers from regional satellite archives. Thirdly, much of the data, especially the Landsat satellite imagery, has for the first time been made available to the users with minimal restrictions, via the employment of open content licensing known as Creative Commons.
