Jones, Lee. Terrestrial LiDAR : Evidence of landscape change (video). 22 May 2012, http://www.youtube.com/watch?v=y4eDguBdCag&list=UU0JCbQti3FlTIzrJGZqzh3Q [Output (Electronic)]
An animation published on the BGS YouTube channel shows an air photo of the Virkisjokull glacier in Iceland from 2007 for initial comparison, and then displays the BGS's 2010 LiDAR-produced Digital Elevation Model (DEM). The volume of landscape change between the 2010 and 2009 DEMs is shown by a colour ramp, where deep blues and purples show surface lowering and reds and yellows show surface rise.
