Remote Sensing Tracks World Water Supply
C|NET reports on NASA-sponsored Gravity Recovery and Climate Experiment (GRACE) which uses two satellites to measure changes in water supply around the world. The information is based on measurements of the Earth’s gravitational field. Small changes are modelled and can reveal “where water is distributed and where it is going.” I for one am please remote sensing is getting such good coverage in the wake of online mapping.
Update 12/13: Corrected misspelling in title, aka removed “Remove Sensing.”
