Not too long ago, I first learned about UNAVCO,a consortium which exists to support university and other research investigators in their use of Global Positioning System (GPS) technology for earth sciences research. The acronym is derived from "University NAVSTAR Consortium", with NAVSTAR being the generic term for and the forerunner of GPS.
UNAVCO has put together a supersite on the Haiti earthquake which contains some spectacular graphics, images, and links.
I'll highlight a couple of these in future posts.
Thanks to my colleague Bob Walter for bringing this site to my attention.
