  • The SPOT-HRS Digital Surface Model (DSM) data was funded by Federal Government, Department of Climate Change. It was completed and delivered by SPOT IMAGE in 2008. The project area covers the coastal areas of Australia with the exeception of areas in North Queensland and Northern Territory. Data was collected and processed as part of the global Reference3D database being developed by SPOT IMAGE. The data was captured using the HRS (High Resoution Stereoscopic) instrument on board the Spot 5 Satellite. This instrument allows for the acquistion of stereoscopic pairs for the purpose of providing Digital Elevation or Terrain Models and Orthoimages. Importantly, while the standard product is termed a Digital Elevation Model (DEM), which in Australia is generally interpreted a being a ground surface, the SPOT-HRS DEM represents the theoretical surface of high points including trees and buildings, commonly referred to as a Digital Surface Model (DSM) in Australia. Data postings are at 1 second of arc, conforming to the DTED level 2 standard. The data projection is geographic, latitude and longitude using a horizontal datum of WGS 84, and a vertical datum of mean sea level as determind by the EGM96 geoid. The absolute horizontal accuracy is 15m at the 90% confidence level, relative horizontal accuracy is 8m at the 90% confidence level. The absolute vertical accuracy at the 90% confidence interval is reported as: 10m in flat rolling terrain < 20 degree slope; 18m in hilly terrain with 20-40 degree slope , and 30m in mountainous terrain > 40 degree slope. Relative vertical accuracy at the 90% confidence interval is reported as: 5m in flat rolling terrain < 20 degree slope; 15m in hilly terrain with 20-40 degree slope , and 28m in mountainous terrain > 40 degree slope. The data is available in DTED and ESRI GRID format at a 1 second (30 metre) grid spacing in 1 degree tiles, 1 second mosaic and also as a 3 second (90 metre) mosaic.

  • These datasets cover approximately 3670 sq km in the central and south eastern sectors of the Rockhampton Regional Council and over all of Great Keppel Island and are part of the 2009 Gladstone 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) - Unclassified LAS - LAS ground classified returns in XYZ - LAS non-ground classified returns in XYZ - 1 metre Digital Elevation Model (DEM) in ASCII xyz - 1 metre Digital Elevation Model (DEM) in ASCII grid - 1 metre Digital Elevation Model (DEM) in ESRI grid - 0.25 metre contours in ESRI Shape

  • 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.

  • The 3 second (~90m) Smoothed Digital Elevation Model (DEM-S) Version 1.0 was derived from resampling the 1 second SRTM derived DEM-S (gridded smoothed digital elevation model; ANZCW0703014016). The DEM represents ground surface topography, excluding vegetation features, and has been smoothed to reduce noise and improve the representation of surface shape. The DEM-S was derived from the 1 second Digital Surface Model (DSM; ANZCW0703013336) and the Digital Elevation Model Version 1.0 (DEM; ANZCW0703013355) by an adaptive smoothing process that applies 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 curvatures that could not be reliably derived from the unsmoothed 1 second DEM because of noise. A full description of the methods is in progress (Gallant et al., in prep) and in the 1 second User Guide. The 3 second DEM was produced for use by government and the public under Creative Commons attribution. The 1 second DSM and DEM that forms the basis of the product are also available as 3 second products (DSM; ANZCW0703014216, DEM; ANZCW0703014182, DEM-S; ANZCW0703014217). <strong>Please note that all 1 second products are available for GOVERNMENT USERS ONLY.</strong>
