Glacier - Greenland

Glaciers are slow moving rivers of ice. Tidewater glaciers, such as this, terminate in the sea, calving off icebergs. Drone survey techniques, using 3D photogrammetry, LIDAR or a combination of the two, can measure the speed of glacial advance, as well as quantify lost mass in high resolution. Though similar observations can be performed by satellite, the coverage in high latitudes may be patchy, and the resolution is poorer and prone to interference by a number of factors. 

Interactive 3D Model

Model navigation and controls

Move camera: 1 finger drag or Left Mouse Button
Pan: 2-finger drag or Right Mouse Button or SHIFT+ Left Mouse Button
Zoom on object: Double-tap or Double-click on object
Zoom out: Double-tap or Double-click on background
Zoom: Pinch in/out or Mousewheel or CTRL + Left Mouse Button
Double-clicking the background also re-centers the model and sets the camera pivot point to the middle of its bounding box. Double-clicking anywhere on the model sets the camera pivot point to that spot.
