UAV form an invaluable help on every work stage. We create orthomosaics and Digital Terrain Models (DTM) used in the designing stage. During the construction we accelerate the process of earthworks inventory. The products we create using UAV are more exact than classic methods and they provide the client with full picture of the constructions site. We can easily inventory dangerous or not accessible sites like excavations in wetlands. We also offer full documentation of works progress in photographs and videos.
