OGS is the owner of an aircraft designed to research and service that enables to carry out missions aimed at acquisition of remotely sensed data (scanning laser, thermal, photo, hyperspectral) and direct samples of the atmospheric column for the determination of air quality (concentration CO2, particulate matter).


The aircraft is a PA - 34 Seneca II twin-engine turbo (makes S5-DGL) six seats, to which was applied an EASA.AS03047 STC (Supplementary Type Certificate) which consists of a hatch 514 x 190 mm from which the optical sensors operate and a dedicated electrical supply system.

The aircraft is certified IFR, has a maximum operating altitude of 25,000 feet and is managed by a company that has all the necessary EASA certification for commercial flight, aerial work and photogrammetric, the aircraft is also under the CAMO (Continuous Airworthiness Maintenance Organization) and is included in the aircraft fleet EU research called EUFAR, a transnational coordinated European infrastructure for air operations with specific address to optical sensors to be applied in the field of the environment and geosciences.

Use and purpose

The plane is used in different configurations for missions both for service and research. Service activities are concentrated primarily in the laser scanning survey integrated with photo shoots: These tools enable to create topographic high quality products that are used in designing infrastructures, monitoring of landslides, surveying power lines. In the course of 2012 there has been increasing demand for photo-plans of the thermal type, i.e. thermal maps that are used to determine the quality of building insulation. Research, with applications both on land and marine, is carried out mainly with environmental sensors (CO2, particulate matter) and optical as the hyperspectral and thermal chamber. For research that requires accurate dimensional information of the area or a deformation monitoring of the same the laser scanner is used. The aircraft has been widely used in missions planned by the EU project Energycity, with the acquisition of thermal and hyperspectral data of seven European cities.
