FLIS is state of art remote sensing infrastructure, which offers simultaneous data acquisition by four sensors. The Flying Laboratory of Imaging Systems (FLIS) consists of an airborne carrier, imaging spectroradiometers and a laser scanner. Photogrammetric airplane Cessna 208B Grand Caravan with two hatches serves as an airborne carrier. The basic sensor equipment consists of hyperspectral sensors CASI-1500, SASI-600 and TASI-600, produced by the company Itres. These sensors are pushbroom scanners that scan the area of interest by individual rows. All hyperspectral sensors are equipped with custom-made sensing chips to ensure higher the so-called "full well capacity" of the detector allowing a higher range of measured signal without saturation. Greater dynamic range allows easier detection of the objects scanned. FLIS is able to operate across the Europe. Hyperspectral sensors are annually calibrated.
