1.0 ItemDescription Queensland Elevation DTM Public Time Series Service This service includes: a) All available 1 metre or 0.5 meter resolution DTMs derived from LiDAR point cloud over Queensland acquired under the Queensland Government Coordinated LiDAR Program (CLP) b) ortho DEM ( DTM or DSM ) over part of Queensland c) Geoscience Australia’s 1 second (30 metre resolution) hydrologically corrected SRTM Digital DEM d) 30 metre, 100 meter and 250 metre resolution Bathymetric data over Queensland coastline and Great Barrier Reef. e) Canopy height model over particular areas. Accuracy is dependent on the projects used. f) Bathymetric data covering parts of the Queensland coastline. For items C and D in this service, all negative values in the SRTM data , and all positive values in the bathymetry data have been removed from the raster. Removing these pixels from the SRTM and the 30, 100 and 250 m bathymetry datasets has resulted in some voids in the coastal areas. Web Service Functions including Aspect, Hillshade, Slope_degrees and Slope_percent_rise are available in none cached service. Additionally stretch and Dynamic Range Adjustment (DRA) can be applied as required through the client to enhance visual contrast. The complete metadata record for this service is available from the Queensland Spatial Catalogue (QSpatial). This service supports projects captured in both GDA94 and GDA2020 datums. A Seven parameter similarity transformation has been applied to new projects that have been captured in GDA2020, this is to ensure that they align and display correctly when published in the default WGS 1984 Web Mercator (Auxiliary Sphere) projection alongside GDA94 projects. The ISO 19115 standard metadata record for this service and further individual epoch mosaic product metadata information is available from the Queensland Spatial Catalogue (QSpatial).
