Airborne scanning LiDAR of sea ice during SIPEX in 2007
2007 was the first season of deployment for the LiDAR by the AAD. While the LiDAR appears to have been working normal, the combination with the INS/GPS was not always optimal. As the INS is critical for determining the orientation of the LiDAR in space, some surveys suffer from bad georeferencing, n...
