Thanks to the ultra-precise characteristics of aerial mapping using commercial-grade PPK-enabled UAVs, Queensland Drones can now deliver precision on-site survey, construction and engineering maps with relative accuracy of 1-2 cm, and geographical accuracy of 3-5 cm, even over very large areas. This is an unprecedented, game changing technology for engineering and construction mapping.
PPK GNSS technology uses multiple clusters of GPS satellites to more accurately determine the location where images are captured. Post processing corrections using physical survey markers, locally surveyed positions and data stream from permanent RTK base stations position the imagery to cm-level and checkpoint measurement by registered surveyors have verified accuracy to 5mm can be achieved using this technology.
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.
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 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 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.
