Gridded airborne laserscanner (ALS) elevation data (L4) for three flights during MOSAiC (prerelease)
An integrated sensor platform including an inertial navigation system (INS) and a commercial (Riegl VQ580) airborne laser scanner (ALS) among other sensor was mounted in the cargo compartment in one of the Polarstern helicopters (D-HARK) during MOSAiC. This sensor combinations allows for a precise m...
