Aerial imaging of sea ice with LiDAR and photos
An integrated airborne imaging system with scanning LiDAR (Light Detecting And Ranging) and high resolution, digital aerial photography is used by the Australian Antarctic Program for various purposes, in East Antarctica. One of the main objectives is the measurement of surface elevation of sea ice...
