Wired News has an interesting article about the use of GPS as an aid in tsunami warnings. Researchers have suggested at least 2 ways in which GPS might give warning information: 1) GPS receivers can measure ground movement in real time, and they could also be used to measure tsunami-associated pressure waves in the Earth’s atmosphere. Either method, when combined with seismic-based warning systems, could help cut down the time before a warning can be issued and increase time for evacuation.
The University Consortium for Geographic Information Science has made a draft of its GI S&T Body of Knowledge (that’s Geographic Information Science and Technology, BTW) available for comment. This document is part of their Model Curricula. Comments can be made on the associated discussion forum on the UCGIS site. While the document is lengthy at 115 pages there are many pages of bullets. The file is available as both a MSWord document for editing and PDF.
