The use of drones is constantly increasing while prices of high-performance drones has fallen. Nowadays, drones can accommodate various complementary optical measuring instruments, such as thermal imagers and photographic imagers. Advanced data communication systems enable real-time wireless data transfer and data processing. .Drones have expanded capabilities for thermography and other optical measurements,. There is a need to develop interpretation keys and data processing techniques. Especially the use of drones is effective when scanning high-rise buildings, but the all the influencing factors must be known and taken into consideration. In this presentation,results and experiences of multi-story apartment houses and other buildings in Finland are presented, along with an evaluation of restrictions and conditions of UAV-based thermal scanning. Also some case studies from USA and the use of outdoor thermography in Russia have been discussed.
