<div>The Abbot Point to Hydrographers Passage bathymetry survey was acquired for the Australian Hydrographic Office (AHO) onboard the RV Escape during the period 6 Oct 2020 – 16 Mar 2021. This was a contracted survey conducted for the Australian Hydrographic Office by iXblue Pty Ltd as part of the Hydroscheme Industry Partnership Program. The survey area encompases a section of Two-Way Route from Abbot Point through Hydrographers Passage QLD. Bathymetry data was acquired using a Kongsberg EM 2040, and processed using QPS QINSy. The dataset was then exported as a 30m resolution, 32 bit floating point GeoTIFF grid of the survey area.</div><div>This dataset is not to be used for navigational purposes.</div>

The Surface Hydrology Points (Regional) dataset provides a set of related features classes to be used as the basis of the production of consistent hydrological information. This dataset contains a geometric representation of major hydrographic point elements - both natural and artificial. This dataset is the best available data supplied by Jurisdictions and aggregated by Geoscience Australia it is intended for defining hydrological features.

North Adelaide Lidar

The data covers an area of approximately 4600 sq km in the Namoi Valley, located around Narrabri, NSW. The LiDAR was captured in September and October 2013 with a point density of two points per square metre. The specified accuracies; 30cm vertical and 80cm horizontal, were achieved and verified through a rigorous network of check points and base stations. A set of seamless products were produced including hydro-flattened bare earth DEMs, DSMs, Canopy Height Models (CHM) and Foliage Cover Models (FCM). The outputs of the project are compliant with National ICSM LiDAR Product Specifications and the NEDF. The survey was conducted over two areas along the Namoi River: one from Boggabri to Narrabri, and the other between Wee Waa and Walgett including a newer extension to this original area to the north east of Wee Waa.

AAM was commissioned by the Department of Primary Industries, Water &amp; Environment to conduct an airborne LiDAR survey over 2 regions known as Coal Mines and Port Arthur. The project area comprises approximately 5.7km². The area was acquired on 14th March 2014.

Background This report describes a project which involved the capture and processing of LiDAR and coincident imagery and resultant derived products for the lower reaches of the Darling River. The data joins two existing LiDAR datasets, one to the north covering the Menindee Lakes and the other in the south along the Murray River corridor. It is intended to provide the Murray-Darling Basin Authority with a very accurate, quality assured measurement of topography in order to accurately model the flow and volume of water in the floodplains within the project area. The LiDAR was captured in April and May 2013 at a point density of two 1st return points per square metre within swath, (equivalent to two outgoing laser pulses per square metre at ground level). The specified accuracies; 30cm vertical and 80cm horizontal, were achieved and verified through a rigorous network of ground check points and base stations. A set of seamless products were produced including hydro-flattened bare earth DEMs, DSMs and cartographic contours. The outputs of the project are compliant with National ICSM LiDAR Product Specifications and the NEDF.

<p>Geoscience Australia conducted a seismic survey in the central Eromanga Basin in Queensland in 1981. This survey was a continuation of the work undertaken in 1980 to investigate the structure, stratigraphy, geological and tectonic evolution, and petroleum potential of the area. The survey obtained 438 km of six-fold Common-Depth-Point seismic reflection data, in the Quilpie Trough and over the Cooper and Thomson Synclines.<p><b>Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74971</b>

Geoscience Australia is responsible for the definition of Australia's maritime boundaries. To assist in this task National Mapping has developed the Australian Maritime Boundaries Information System (AMBIS). AMBIS 2001 is a data product, derived from AMBIS, providing access to the data for Australia's Territorial Sea Baseline (TSB) and maritime zones. AMBIS 2001 data comprises the TSB and the outer limits of each zone, together with quality attributes. Base points that generate the zone boundaries are supplied in separate files and an extensive user guide provides useful background information. All data coordinates are supplied in the Geocentric Datum of Australia (GDA 94) which is effectively identical to the WGS84 datum. National Mapping is committed to the maintenance of the AMBIS data to ensure it reflects the changing nature of Australia's coastline and hence the various maritime zone limits. To this effect, a newly revised AMBIS 2001 product (version 1.1) has been released in October 2001. This new version incorporates additional treaty information, additional data in the vicinity of Swains Reef in Queensland, an improved representation of the TSB, several other minor corrections, a wider range of formats and simplified attribute tables.

The Officer Basin project was a co-operative project jointly conducted by Geoscience Australia (GA) and the South Australian Department of Mines and Energy (DMESA) as part of the National Geoscience Mapping Accord (NGMA). The goals of the 1993 seismic acquisition in the Officer Basin were to provide a regional network of traverses to develop a cross section and evaluate basin morphology. The acquisition was designed to image the basin fill, with the aim of extending the stratigraphic control in the eastern Officer Basin into the central portion of this basin. The survey comprised five lines totalling 550 km in length. In 2021, Geoscience Australia commissioned reprocessing of these legacy 2D seismic data as part of the Exploring for the Future (EFTF) program, to improve data quality and better image reflective structural features in the region. Velseis Processing Pty Ltd carried out the reprocessing from March to August 2021. GA managed the reprocessing project, undertook quality control of the data processing and archived the processed data. This dataset includes metadata, images and SEGY files for pre-migration stacks, pre-stack time and depth migration stacks, and post-stack migration data. The images and SEGY files are derived from the Velseis final SEGY files. The reprocessed dataset is available for download. <b>Raw data and the Velseis data package for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 74944</b>
