Airborne lidar for mountain and forestry surveys

April 26th, 2018, Published in Articles: PositionIT

Asia Air Survey in Japan has taken delivery of a Teledyne Optech ALTM Galaxy T1000 for use in their forest resource management initiatives, road and railway facility management, as well as slope stability monitoring activities. With 70% of Japan covered in mountains and hillsides, the country can be very susceptible to geomorphic hazards, such as landslides, often caused by seismic activity. To predict and mitigate these hazards, AAS plans to use the airborne lidar sensor to collect high-density 3D data to create detailed maps of the country. The Galaxy is designed to collect high-accuracy data in variable and forested terrain, using its full-waveform capability and SwathTrak technology. The SwathTrak function dynamically changes the scan angle in the air according to height above ground, making the measurement width constant. This makes it possible to reduce the number of flight strips and to reduce the flight cost.
