Vision Surveys QLD is thrilled to announce our collaboration with Jigme Thinlye, a PhD student at Griffith University! Jigme is researching innovative solutions in forestry, carbon sequestration and bushfire mitigation research using our advanced UAV LiDAR and aerial imagery sensors. In this study, Vision captured and processed high-resolution drone lidar and aerial imagery for the production of digital elevation models (DEM) (true ground), digital surface models (DSM) (top of canopy/vegetation), as well as orthorectified photos of the study site and the original point cloud to model biomass between the ground to the canopy top. Key highlights from the study: ▶️ Tree top detection: utilised a moving window algorithm. ▶️ Tree stand characteristics: calculated average crown height, radius and canopy break height using canopy height models (CHM) and zonal statistics. ▶️ Forest characteristics: estimated number of crowns, total crown area, density of crowns and Above Ground Biomass (AGB): estimated cumulative AGB per hectare using the current models. Check out the insightful images from the study, including the orthorectified photo, canopy height model, tree locations and estimated tree crowns. This collaboration showcases our advanced drone and LiDAR technology, combined with leading researchers, to provide essential datasets for ecological research and forest management. Special thank you to Jigme’s PhD supervisors Professor Catherine Pickering and Dr Christopher Ndehedehe, PhD for their support in this project. Stay tuned for more updates as we continue to push the boundaries of what's possible with quality UAV LiDAR! #VisionSurveysQLD #GriffithUniversity #UAVLiDAR #DroneImagery #ForestryResearch
