Using the ultra-precise characteristics of commercial-grade PPK-enabled aerial mapping UAVs combined with precisely surveyed ground control, Queensland Drones can now deliver cm-precision on-site survey, construction and engineering maps with relative (local) accuracy of 1-2 cm, and a spatial (geographic) accuracy of 2-5 cm, even over very large areas. This is an unprecedented, game changing technology for engineering and construction mapping.
Working with your preferred surveyors (or ours) and using enterprise-grade PPK GNSS technology, we’re able to accurately determine the precise location for every captured image and correct overall positioning in post-processing using professionally surveyed ground control points and checkpoint markers to deliver survey grade accuracy of 5-8mm where required. Even without the involvement of a registered surveyor, our PPK precision mapping outputs are typically accurate to a few centimetres. Pay only for what you need!
Precision Aerial Orthographic Mapping
The ability to closely follow terrain contours and tag every single photo with precision PPK location data means the precision PPK drones used by Queensland Drones can capture incredibly detailed and precise orthographic imagery even over very large areas.
Imagery so accurate, you can overlay CAD design drawings to check for variations between the “as-built” and the original design to validate completion of earthworks and estimate remaining volumes to remove or relocate.
Precision Digital Surface Model Mapping
Using PPK-equipped UAVs, Queensland Drones can create incredibly detailed and precise orthomosaic imagery and deliver equivalently precise and detailed ground-classified Digital Surface Models (DSMs) to represent the terrain of the captured area with vegetation removed. Use the slider in the image above to compare the orthomosaic and DSM mapping results.
Precision Planimetric Feature Mapping
Our aerial imagery is so precise and detailed that we can extract precision planimetric features from the orthomosaic to identify road verges, kerbing, power poles, intersection design features, driveways, fences and more to speed up your design workflows.
Precision Mining and Quarry Mapping
For mining and quarry mapping, our precision PPK UAVs can deliver incredibly detailed 3D digital models of the terrain including detailed imagery inside the open pit and the ability to precisely measure features like face heights and slopes. Queensland Drones can collect and deliver this detail up to 13 times faster than conventional methods and with minimal disruption to mine operations.
RedEdge Multispectral Vegetation Mapping
Our advanced VTOL fixed wing UAVs are also able to capture visual and spectral analysis of vegetation in mine rehabilitation sites, infrastructure corridors, farms and plantations. The images above show a detailed orthographic view of a large plantation, with corresponding multispectral analysis of the relative health of each part of the plantation using our multispectral RedEdge sensor. Queensland Drones can deliver detailed analysis for NDVI, Red Edge (NDRE), Green NDVI, Blue NDVI, Red NDVI, CIR, OSAVI and more. We can also deliver raw spectral layer data in ESRI compatible formats for analysis by your own GIS team.
