The offshore Gippsland Basin is Australia's major producing hydrocarbon province. Acreage has historically been tightly held, and opportunities for new players in this highly prospective basin have been limited. However, recent relinquishments have allowed the Australian Federal and Victorian State Governments to offer three potential permits to petroleum exploration companies and consortia. The Bureau of Mineral Resources Petroleum Group, in collaboration with the Victorian Department of Manufacturing and Industry Development's Petroleum Branch, has produced a hydrocarbon prospectivity package for the Southeast Gippsland Basin, with particular emphasis on the three areas to be released. The package takes the form of this BMR Record 1991/9. The Package covers regional geology, geophysics, palaeogeography, and hydrocarbon play concepts, together with a new structural interpretation for the Gippsland Basin developed at BMR. In addition, for each release area the package covers previous exploration, local geology and play concepts, reservoir geology and engineering, and geohistory. Prospects and leads are described in detail, and the text is complemented by some 80 Plates and Figures.

This report deals with the results of 25,000 ft. of boring over an area of 15 sq. miles. Twenty-six coal seams were identified and named. Total reserves of all seams with band-free thickness greater than 4.0 ft. are 200,000,000 tons. Net open-cut reserves (to 9:1 ratio) of 7,500,000 tons over an area of 400 acres were tested and defined on four seams. All work in the Howick Area was done in the period March, 1952, to June, 1953.

Geoscience Australia has created a seamless national 1-second Digital Elevation Model with consistent resolution, elevation units, and projection, incorporating the best possible source data. Data sources include the 1-second Shuttle Radar Topography Mission (SRTM) data as a baseline, and higher resolution LiDAR-derived data where available. The SRTM and LiDAR platforms produce data with very different horizontal resolutions: 1-second (approximately 30-metres) and 1-metre respectively. The vertical resolution of the datasets varies from 5-metres to 15-centimetres. In order to combine these datasets the higher resolution LiDAR is resampled to the same horizontal resolution as the SRTM dataset. The two platforms use different sensors, and detect different features. Some of the above-ground features can be automatically removed from the SRTM dataset while nearly all are removed from the LiDAR dataset. This leads to a discontinuity between the datasets that must be handled when mosaicking the two datasets together. There are several standard mosaic methods available, but none of them work suitably when combining these datasets. The elevation difference between these datasets has been overcome by using a distance-weighted mean mosaic method. This method applies a mean mosaic method that favours one dataset over the other depending on how far the seam line between the datasets is: if a point is near the edge of the LiDAR dataset, then the elevation is more similar to the SRTM dataset, and vice versa. This mosaic method has been applied to all of GA's LiDAR data holdings to create a new 1-second DEM covering all of Australia.

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.
