Studies that implement different sorts of unmanned aerial vehicle (UAV) in forestry are more frequent due to the higher availability and lower prices of modern UAV technologies. In that manner, Institute of Lowland Forestry and Environment, started utilization of Phantom 3 quadrocopter through activities of mapping and creation of 3D models. Images captured at Real Estate of the Institute, consisted dominantly of poplar plantations, before tree felling where used for creation of 3D model with OpenDroneMap software. Further processing and editing 3D triangular model meshes were performed with software MeshLab and final measurements were obtained with software Blender. Verification of tree heights were performed with direct measurements of fallen trees. Assessed tree heights from 3D model obtained with UAV Phantom 3 and open-source software were within 10% error. Despite relatively imprecise initial measurements, there is a large room for improvement and high potential of UAV application in forestry.
