This digital terrain model (DTM) represents the bare ground surface or depth without any objects like trees and buildings. This service comprises the latest publicly available 0.5 and 1 metre resolution LiDAR DEMs over Queensland acquired under Queensland Government coordinated acquisition programs, Geoscience Australia’s 1 second (30 metre resolution) hydrologically corrected SRTM Digital DEM, and 30, 100, 250 meter resolution bathymetric data. Accuracy is dependent on the projects used. This Limited Error Raster Compression (LERC) tile cached service, which handles tiles that connect through multiple levels of details, is built for 3D content scenes, elevation profiles, and is specialised for elevation surface data to extract per pixel height values. Web Service Functions including Aspect, Hillshade, Slope_degrees and Slope_percent_rise are available in cache-disabled service in ESRI desktop clients. Additionally stretch and Dynamic Range Adjustment (DRA) can be applied, in both the cache-enabled and cache-disabled service, as required through any client to enhance visual contrast. The complete metadata record for this service is available from the Queensland Spatial Catalogue. 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.
