<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.

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.

AAMHatch has been engaged by Geoscience Australia to undertake a LiDAR survey over the BHMAR Phase 2 project area, for the purpose of producing a DTM and vegetation structure analysis. The survey covers an area of approximately 7856 sqkm of the Lower Darling River, downstream from Wilcannia. To this end, LiDAR data was acquired from a fixed wing aircraft between June 19th and August 5th 2009.

The coverage of this dataset is over the WestNarranLake region . The C3 LAS data set contains point data in LAS 1.2 format sourced from a LiDAR ( Light Detection and Ranging ) from an ALS50 ( Airborne Laser Scanner ) sensor . The processed data has been manually edited to achieve LPI classification level 3 whereby the ground class contains minimal non-ground points such as vegetation, water , bridges , temporary features , jetties etc . Purpose: To provide fit-for-purpose elevation data for use in applications related to coastal vulnerability assessment, natural resource management ( especially water and forests) , transportation and urban planning . Additional lineage information: This data has an accuracy of 0.3m ( 95 CI ) vertical and 0.8m ( 95 CI ) horizontal with a minimum point density of one laser pulse per square metre . For more information on the datas accuracy, refer to the lineage provided in the data history .

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.

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.

The survey 1999 CABGAS 2D seismic Survey was contracted to Terracorp Pty Ltd for Australian National Seismic Imaging Resource (ANSIR). The survey operation consisted of 160 kilometres of seismic line in the unassigned acreage of the Darling Basin area, located approximately 150 kilometres north east of Broken Hill in western New South Wales. Raw data for this survey are available on request from clientservices@ga.gov.au

The data covers an area of approximately 8500 sq km in the Darling river catchment area, located between Bourke, NSW and Wilcannia, NSW. 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.
