The Cessna T206H single-engined, general aviation aircraft with fixed landing gear, used in commercial air service. This aircraft continues to be one of the best performing aerial survey aircraft offering efficiency as well as capability at low and high altitude and is ideal for LiDAR capture. This platform houses a camera cowling for Lidar / imaging acquisition. This aircraft is a very flexible and affordable survey solution.

SGI operates the Cessna 206T for PT Surtech Prima, a reputable airborne mapping company, specializing in high-resolution elevation and photo acquisition. The Cessna T206H turbine aircraft is modified with a survey hole which allows us to mount our state-of-the-art equipment for collecting very accurate terrain information and sharp imagery of the areas surveying.
Airborne laser scanning, or LiDAR, collects data using a powerful laser and precise GPS and positional information from satellites and on-board inertial positioning systems. The equipment will detect multiple returns from each emitted laser pulse, recording points along the vegetation profile and at the ground surface. Using the time difference between each sent and returned laser pulse, which is recorded by a very sensitive clock, the elevations can be calculated at a vertical accuracy of less than 10cm. The imagery is collected by a 100 megapixel medium format camera, which can output a pixel resolution of 8cm based on our survey altitudes. The technology is capable of capturing over 5,000 hectares per day, collecting millions of elevation points regardless of the terrain or vegetation. The spatial data is post-processed using sophisticated software to produce several client deliverables including Digital Terrain Models (DTM), Digital Surface Models (DSM), contours, and ortho-rectified imagery.
