Lidar Instrument and Pod
For the 2015 acquisition we’re using a Leica ALS70 lidar instrument with full waveform capability, mounted to the right skid of a Eurocopter AS350 B2 “Squirrel” helicopter. For the install we have to remove much of the interior of the chopper and replace it with special computers, power supplies, GPS upgrades and additional avionics. The helicopter is the same one that’s used for tourist flights around the Angkor Archaeological Park, and the same helicopter we used last time in 2012, although the lidar instrument we’re using this time around is capable of much greater point densities than the ALS60 instrument that we deployed last time. We also have a 40 megapixel Leica camera looking straight down as well as a forward-facing Canon EOS 5D at the front of the pod to take oblique aerial shots of what we’re flying towards. Our lidar data provider both times has been the Indonesian branch of the Canadian survey engineering company McElhanney.
