Respect the Roundness

Posted by – January 30, 2013


NOAA and several commercial vendors have developed spherical displays of geoscience and mathematics that are both beautiful and thought provoking, allowing us to see phenomena like ocean currents, trade, climate, and geology evolving over time without the distortions of a 2-D projection. Examples in the video include (starting at 6:25) an animation of pollutants crossing the North Pole and (starting at 7:45) a depiction of continental drift from Pangea to present day. If you want to explore the datasets on your home computer, NOAA provides KML files for display using GoogleEarth.

Cheers to Dori for the tip!
