  • 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.

  • <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>

  • Aerometrex - Adelaide was contracted by Department for Environment and Heritage to capture data along the Murray River from Lock 1 to Wellington

  • High resolution elevation data covering an area of approximately 12,600 sq km in the Wakool-Murray catchment area. The survey is situated along the Victoria and NSW border, located between Yarrawong, Echuca, Robinvale and Moulamein and Deniliquin. A set of products were produced including classified lidar point clouds, 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 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.

  • This document details the methods and results of the project Adelaide LiDAR Classification and Derived Products¿ performed by RPS for Geoscience Australia in 2013. Lineage and Accuracy Statements for ANZLIC metadata documents for each of the project deliverables are included. Airborne LiDAR data was acquired over Adelaide in September 2008 and North Adelaide in September 2011. Differences in the level of classification reduced the ability to integrate the data into an accurate, seamless and consistent coastal DEM suitable for detailed modelling the potential impacts of coastal inundation or riverine flooding. The objective of this project was to reclassify both the 2008 and 2011 point clouds to ICSM Level 3 and derive hydro flattened 1m bare earth DEMs and; 0.25m cartographic contours, all inline with the ICSM LiDAR Acquisition Specifications. Figure 1. Adelaide LiDAR Reclassification 2012 overview map The LiDAR The LiDAR was provided as tiled LAS files. RPS did not apply any vertical or horizontal adjustments to the LiDAR and is unable to comment on the spatial accuracy of the point cloud. The deliverables were: Classified ICSM Level 2 and Level 3 point clouds in LAS format 1 metre DEMs in ESRI Binary grid format 0.25 metre contours in ESRI Shape format Break lines in ESRI Shape format. This report All files were named according to the ICSM file naming specifications.

  • AusAEM (WA) 2020-21, Earaheedy & Desert Strip Airborne Electromagnetic Survey The accompanying data package, titled “AusAEM (WA) 2020-21,Earaheedy & Desert Strip Airborne Electromagnetic Survey Blocks: TEMPEST® airborne electromagnetic data and GALEI conductivity estimates”, was released on 25 March 2021 by Geoscience Australia (GA) and the Geological Survey of Western Australia. The data represents the first phase of the AusAEM2020 (WA) survey flown with a fixed-wing aircraft by CGG Aviation (Australia) Pty. Ltd. under contract to Geoscience Australia, using the TEMPEST® airborne electromagnetic system. The survey was flown at a 20-kilometre nominal line spacing over the most eastern part of the state and down to the southern coast of Western Australia. The total area encompasses close to 32,680 line kilometres of newly acquired airborne electromagnetic geophysical data. CGG also processed the data. This package contains 14,279 line kilometres of the survey data, which have been quality-controlled, processed and inverted. The Earaheedy Block entailed approximately 6,407 line kilometres and the Desert Strip 7,870 line kilometres. The remaining data will be released as a separate package. Geoscience Australia and Western Australia (Department of Mines, Industry Regulation and Safety) commissioned the AusAEM 2020 survey as part of the national airborne electromagnetic acquisition program, to complete 20km line separation AEM coverage over WA. The program is designed to deliver freely available pre-competitive geophysical data to assist in the investigation and discovery of potential mineral, energy and groundwater resources within Australia. Funding for the survey came from the Western Australian government’s Exploration Incentive Scheme. GA managed the survey data acquisition, processing, contracts, quality control of the survey and generated the inversion products included in the data package. The data release package contains 1. A data release package summary PDF document. 2. The survey logistics and processing report and TEMPEST® system specification files 3. ESRI shapefiles for the regional and infill flight lines 4. Final processed point located line data in ASEG-GDF2 format 5.
