Moreton Bay 2009 LiDAR data was captured over the Moreton Bay Regional Council area between March and June 2009. The data was acquired by AAM Hatch (now AAMGroup) and funded by Queensland and Commonwealth governments. The project area covering 2440sqkm is licenced for use by all Commonwealth, State and Local Government organisations. Data acquisition and post-processing has been controlled to achieve a vertical accuracy witihn 0.15m (RMS, 68% CI) and horizontal accuracy within 0.45 m. Horizontal coordinates are based upon Map Grid of Australia (MGA) Zone 56 projection. Vertical coordinates are referenced to Australian Height Datum (AHD). The data was captured with point density of 2.5 points per square metre and the data is available as mass point files (ASCII, LAS) and ESRI GRID files with 1m grid spacing in 1km tiles.

Redland 2009 LiDAR survey was captured over the Redland City Council region between 25th March and 9th June 2009. The data was acquired by AAM Hatch (now AAMGroup) and funded by Queensland and Commonwealth governments. The data is licensed for use by all Commonwealth, State and Local Government. Data acquisition and post-processing has been controlled to achieve a vertical accuracy within 0.15m (RMS, 68% CI) and horizontal accuracy within 0.45 m. Horizontal coordinates are based upon Map Grid of Australia (MGA) Zone 56 projection. Vertical coordinates are referenced to Australian Height Datum (AHD). The data was captured with point density of 2.5 points per square metre and the data is available as mass point files (ASCII, LAS) and ESRI GRID files with 1m grid spacing in 1km tiles. The data are available as a number of surface types, products and formats including: mass points, digital elevation model (DEM) and hydrologically enforced DEM (HDEM) for the low lying coastal areas. Redland DEM forms part of the Brisbane HDEM which is a combination of the Brisbane 2009 LiDAR, Redland 2009 LiDAR, Moreton Bay 2009 LiDAR and Logan 2009 LiDAR survey areas.

South East Queensand (SEQ) 2009 LiDAR data was funded by Queensland Department of Environment and Resource management (DERM) , which was captured and delivered by AAMHatch between March 25th 2009 and June 9th 2009. The project area covering 5300 sqkm was divided into three sub areas, namely South East Queensland Priority Area, Gold Coast and the Balance of SEQ. Data acquisition and post-processing has been controlled to achieve a vertical accuracy witihn 0.15m (RMS, 68% CI) and horizontal accuracy within 0.45 m. Horizontal coordinates are based upon Map Grid of Australia (MGA) Zone 56 projection. Vertical coordinates are referenced to Australian Height Datum (AHD). The data was captured with point density of 2.5 points per square metre and the data is available as mass point files (ASCII, LAS) and ESRI GRID files with 1m grid spacing in 1km tiles and inundation contours (0.25m). A hydrologically conditioned and drainage enforced 2m DEM or HDEM has also been developed in 2010 as part of the Urban DEM project managed by the CRC for Spatial Information and Geoscience Australia. The HDEM was produced by SKM using the ANUDEM program. Hydrologic enforcement and conditioning has included the testing of data for sinks, the referencing of transport and hydrology vector layers for intersections and flow, and the use of high-resolution imagery for visual validation. The methodology for hydrologic enforcement has required deriving a stream network based on flow direction and accumulation, using TIN and ANUDEM processes to analyse sinks and artificial damming affects caused by objects such as roads, bridges and trees which have not been previously filtered. Break lines have been included via the insertion of culvert/drainage channels, which has been used to interpolate these features into the main DEM as descending grid values. All data are referenced to GDA94/MGA Zone 56.

These datasets cover approximately 260 sq km along the eastern seaboard of the Cook Shire Council and over all of Lizard, Palfrey and South Islands and are part of the 2009 North Queensland LiDAR capture project.

The Harvey 2008 LiDAR data was captured over the Harvey region during February, 2008. The data was acquired by AAMHatch (now AAMGroup) and Fugro Spatial Solutions through a number of separate missions as part of the larger Swan Coast LiDAR Survey that covers the regions of Perth, Peel, Harvey, Bunbury and Busselton. The project was funded by Department of Water, WA for the purposes of coastal inundation modelling and a range of local and regional planning. The data are made available under licence for use by Commonwealth, State and Local Government. The data was captured with point density of 1 point per square metre and overall vertical accuracy has been confirmed at <15cm (68% confidence). The data are available as a number of products including mass point files (ASCII, LAS) and ESRI GRID files with 1m grid spacing. A 2m posting hydrologically enforced digital elevation model (HDEM) and inundation contours has also been derived for low lying coastal areas.

<p><b>Removed from distribution 21/04/2020 on request from Kevin Kennedy</b> <p>The 3 second (~90m) Shuttle Radar Topography Mission (SRTM) Derived Digital Elevation Models Version 1.0 package comprises three elevation models: the Digital Surface Model (DSM; ANZCW0703014216), the Digital Elevation Model (DEM; ANZCW0703014182) and the Smoothed Digital Elevation Model (DEM-S; ANZCW0703014217). The DEMs were derived from re-sampling the 1 second SRTM models derived from the SRTM data captured by NASA in February 2000, supported by the GEODATA 9 second DEM in void areas and other supplementary layers. <p>DSM represents the ground surface topography as well as features above the ground, such as vegetation and man-made structures. Stripes and voids have been removed from the 1 second SRTM data to provide an enhanced and complete DSM for Australia and near-shore islands. <p>DEM represents ground surface topography, with vegetation features removed using an automatic process supported by several vegetation maps. This provides substantial improvements in the quality and consistency of the data relative to the original SRTM data, but is not free from artefacts. Man-made structures such as urban areas and power line towers have not been treated. The removal of vegetation effects has produced satisfactory results over most of the continent and areas with defects identified in supplementary layers distributed with the data, and described in the User Guide. <p>DEM-S represents ground surface topography, excluding vegetation features, and has been smoothed to reduce noise and improve the representation of surface shape. An adaptive smoothing process applied more smoothing in flatter areas than hilly areas, and more smoothing in noisier areas than in less noisy areas. This DEM-S supports calculation of local terrain shape attributes such as slope, aspect and curvature that could not be reliably derived from the unsmoothed 1 second DEM because of noise. <p>The 3 second DEMs do not include the hydrologically enforced product, which is only available in 1 second resolution. The 3 second DEMs were released under Creative Commons attribution licensing in ESRI Grid format. Further information can be found in the supplementary layers supplied with the data and in the User Guide.

Metadata acquired by GA for the purposes of the National DEM Project from WA Landgate. DEMs are a mass of ground heights representing a terrain surface. In this instance they are spaced at a regular grid interval. This dataset has been developed from aerial photography to assist in the digital imagery Orthorectification program. The status of coverage or other information relative to specific DEM data may be obtained directly through the DOLA contact.
