These datasets cover approximately 1100 sq km in the central sector of the Hinchinbrook Shire Council and over all of Orpheus Island and are part of the 2009 Tropical Coast LiDAR capture project. This project, undertaken by Fugro Spatial Solutions Pty Ltd on behalf of the Queensland Government captured highly accurate elevation data using LiDAR technology. Available dataset formats (in 2 kilometre tiles) are: - Classified las (LiDAR Data Exchange Format where strikes are classified as ground, non-ground or building) - 1 metre Digital Elevation Model (DEM) in ASCII xyz - 1 metre Digital Elevation Model (DEM) in ESRI ASCII grid - 0.25 metre contours in ESRI Shape

AAMHatch acquired Airborne Laser Scanning (ALS) data for the Sydney Metropolitan area between 11 June 2007 & 7 July 2007 and again in February to June 2008. The source data are available as mass points (ASCII XYZ, LAS) and Gridded 2m and 10m DEM tiles or 2m Mosaic. The vertical accuracy is 0.15m at 1 sigma in open clear ground as specified in the project scope. All data are referenced to GDA94/MGA Zone 56 and AHD using independent survey control which means the project area is not seamless and height difference between the 2007 and 2008 data will exist. A hydrologically enforced elevation model is available for this product, which should be used for any water modelling.

These are high resolution 5 metre Digital Terrain Model spatial partitions generated from the Land Information Centres Large Scale Contour Archive. The partitions are 9 kilometers by 7.5 kilometres and align to the ISG 1:10000 zone coverage of New South Wales. This theme contains DTM`s created from existing 2 metre contours sourced from the 1:4000 Orthophoto Map Series of the NSW topographic map archive . Beginning date: 01 February 1998 (1998-02-01) Ending date: 01 August 1999 (1999-08-01)

Abstract: 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 . The status of coverage is available either directly or via remote access to Land Monitors website http://www.landmonitor.wa.gov.au/ Information relative to specific DEM data may be obtained directly through the Landgate contact. This DEM data has been generated from a wide range of aerial photography) by Landgate WA (formerly WA Dept. of Land Information). As a result, there are various associated photoscales and acquisition dates. The DEM has been supplied to the ATWS for the purpose of modelling and have been mosaiced into pre-determined areas by Landgate based on the ATWS research. DEM's and contours are available in a number of formats. Metadata and Licence conditions supplied. Internal requests for the data should be addressed to the ATWS. Other requests should be addressed to DLI Western Australia.

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.

Adelaide LiDAR 2008 data was flown by AAMHatch between 13th to 19th September 2008 as part of the Urban Digital Elevation Modelling in High Priority Areas Project funded by the Federal Department of Climate Change. Several data gaps existed in the intital survey due to operational instrumentation errors and a subsequent refly was conducted on 5th January 2009 to complete the dataset. The data was captured with point density of 0.8m point per square metre and overall vertical accuracy has been confirmed at <15cm (68% confidence level). The data are available as mass point files (LAS) comprising ground, thinned ground and non ground points in 2km tiles. 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. The HDEM ensures that primary stream/channel flow, and water flow across the land surface are accurately represented. The hydrologically enforced elevation model should be used for any water modelling. Adelaide Hydrological Enforced DEM(HDEM) 2008

The Adelaide 2009 LiDAR data was captured over the Adelaide coastal metropolitan area between 13th and 19th of September 2008. Some data were re-flown on the 5th of January 2009 due to instrument errors and data gaps. The data were acquired by AAMHatch (now AAMGroup), and purchased by the Commonwealth Department of Climate Change and Energy Efficiency under licence for use by Commonwealth, State and Local Government organisations. The data was captured with a point density of 0.8 points per square metre. Overall vertical accuracy has been confirmed at <15cm (68% confidence level). The data are available as mass point files (LAS) comprising ground, thinned ground and non ground points in 2km tiles in addition to a gridded DEM and hydrologically enforced DEM or HDEM. The hydrologically conditioned and drainage enforced 2m DEM or HDEM was 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. The HDEM ensures that primary stream/channel flow, and water flow across the land surface are accurately represented. The hydrologically enforced elevation model should be used for hydrological modelling.

The Kurnell 2008 LiDAR Survey was captured over Kurnell Peninsula (south of Sydney) on 8 December 2008. The source data was captured by AAM Hatch and funded by New South Wales, Department, Land & Property Management and made available under licence for use by Commonwealth, State and Local Commonwealth Government. The vertical accuracy is 0.15m at 1 sigma in open clear ground as specified in the project scope and 0.3m in the horizontal. All data are referenced to GDA94/MGA Zone 56 and AHD. The source data are available as mass points (ASCII XYZ, LAS) and Gridded 1m DEM tiles or 1m or 10m mosaic. A hydrologically enforced elevation model is available for this product, which should be used for any water modelling. Sydney Hydrological Enforced DEM (HDEM) 2007-2008 is a combination of this dataset and the 2007 & 2008 Sydney LiDAR datasets adn should be used for hyrological modelling.

These datasets cover approximately 90 sq km over the Town of Doomadgee, straddling the boundary between the Burke and Doomadgee Shire Councils and are part of the 2010 Gulf LiDAR capture project. This project, undertaken by Vekta Pty Ltd on behalf of the Queensland Government captured highly accurate elevation data using LiDAR technology. Available dataset formats (in 1 kilometre tiles) are: - Classified las (LiDAR Data Exchange Format where strikes are classified as ground, vegetation or building) - 1 metre Digital Elevation Model (DEM) in ASCII xyz - 1 metre Digital Elevation Model (DEM) in ESRI grid - 1 metre Digital Elevation Model (DEM) in ASCII grid - 0.25 metre contours in ESRI Shape

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. 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. The hydrologically enforced elevation model should be used for any water modelling. Adelaide Hydrological Enforced DEM(HDEM) 2008
