It is an AS350AB operating survey mission with Lidar.
Assuming that means an AS350BA, Helitrans have two LN-OMY (serial 1017) and LN-ORK (1056) according to official data at 1st November. They also have one B1 and nine B3s.
I find a photo of LN-OMY looking like it may be fitted to take LIDAR stuff - although that does NOT confirm it as the subject helicopter which is being searched for.
