This time-series elevation service is designed to provide access to publicly
available highest resolution, ortho Digital Terrain Model (DTM) data captured
by remotely piloted aircraft systems (drones), piloted aircraft, and the
Shuttle Radar Topography Mission (SRTM) and bathymetric data over areas of
Queensland. 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 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.
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.
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.
