Inside Science Buzzwords:

  1. LIDAR - Short for Light Detection and Ranging, a remote-sensing technique that measures distances such as the depth of floodplains by bouncing laser light off objects. 
  2. T-LIDAR - Stands for Terrestrial Light Detection and Ranging; a remote-sensing technique that measures the height or mountain peaks or depths of valleys bouncing laser light off objects.
  3. Terrestrial - Related to Earth or land. 
  4. StarCAVE - A virtual reality room where scientific data, such as information from T-LIDAR, is projected on multiple display screens giving the viewer the ability to see the information in 3D. 
  5. Virtual Reality - A computer-generated environment that can replicate physical elements in a space, creating an imaginary world for the user.
