Infrared aerial images — Digital CIR orthophotos of the city of Braunschweig from the photo flight 2020

In a digital flight on 18 March 2020, hundreds of individual images were taken vertically from an aircraft. The high-resolution images with 8 cm bottom pixels were digitally equalised and matched precisely using GPS data. Parallel to the images in real colors (RGB), so-called false color or infrared images (CIR) were taken simultaneously via special infrared channels of the aerial camera during the flight.
