The Brisbane hydrologically enforced digital elevation model (DEM) was created from a combination of the following surveys; Brisbane 2009 LiDAR, Redland 2009 LiDAR, Gold Coast 2009 LiDAR, Moreton Bay 2009 LiDAR and Logan 2009 LiDAR survey areas. The data is licensed for use by all Commonwealth, State and Local Government. Data acquisition and post-processing for all of the input surveys has been controlled to achieve a fundamental vertical accuracy of <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 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.

These datasets cover approximately 72 sq km over a strip of land joining the Town of Burketown to the Coast within the Burke Shire Council 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

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.

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.

This data disk contains SunRISE 21 Licensed Data prepared for: - CLIENT: Geoscience Australia / CRC LEME - SUPPLY DATE: 30/8/2006 - Under Terms and Conditions of Data Licence Agreement(DLA): 0046 OR as set out below The data has been derived photogrammetrically from aerial photography: - Date of Photography: Various - Scale of Photography: Various DATUM: - Horizontal Datum: GDA94 MGA54 - Vertical Datum: AHD (Australian Height Datum) ABOUT the CONTOURS / DEM: - DEM: 10m x 10m height grid points - Contour Interval: 1 metre form lines derived from 2 metre contours. The contours have been interpolated from the height grid, and a smoothing spline fitted. ACCURACY ESTIMATE: - Horizontal 0.5 metres Vertical 1.0 metre In areas subject to dense vegetation, shadow or where the terrain is not confidently visible, the stated horizontal and vertical accuracy should be regarded with caution.
