Remote sensing techniques including imaging spectroscopy, have been and are still widely used for measuring physical quantities and studying physical phenomena. By taking advantage of the different reflective, refractive and diffractive properties of different media, physical information can be extracted from the spectral information recorded by instruments. Worldwide this is utilised in various applications studying anything from molecular composition to nematodes in fish filets to the nature of distant galaxies. Airborne imaging spectroscopy has several interesting areas of applications, especially in the Svalbard area where distances and environmental limitations require remotes sensing. Among these are: control of fishing, monitoring of pollution both in the air, at ground and at sea, identication of people and equipment in search and rescue operations and classification of ground (for mapping).
For this campaign two different platforms have been used. The main and well tested platform used is mounting the instrument in a Dornier 228-202K airplane operated by the commercial company Lufttransport AS. The instruments are looking out of a sliding door at the side of the airplane, pointing 30 degrees off Nadir. The second platform tested was the so-called CryoWind UAV system developed by Norut IT in cooperation with among others, UNIS. It consists of a lightweight instruments package mounted onboard an unmanned aircraft (model airplane). The first test of the DRONESPEX spectrometer was done during the AIRSPEX MMVI campaign. Two different experiments were tested onboard the main platform. One was the spectrometers BIGSPEX and DRONESPEX with additional data from digital cameras (SLR cameras and others), and the second was the GPSCAM Iridium experiment, allowing you to tag images with GPS and gyro information and sending them through an Iridium phone.
