Nasa creates incredible video 'fly-through' of 18-mile crack in Pine Island glacier from 3D laser sc

In October 2011, airborne Nasa researchers made the first-ever detailed 3D measurements of a major iceberg calving event - a new iceberg 'being born'.

The IceBridge team has now used the measurements - captured with a 3D laser imaging device - to create a 3D model of the crack in Pine Island Glacier, and an incredible video of what it would be like to fly through.





 The animation was created by draping aerial photographs from the Digital Mapping System - a still camera with very precise geolocation ability—over data from the Airborne Topographic Mapper - a scanning laser altimeter that measures changes in the surface elevation of the ice.
Both instruments were flown on NASA's DC-8 research airplane, and the data was collected on October 26, 2011.
The crack formed in the ice shelf that extends from one of West Antarctica’s fastest-moving glaciers.
