In epidemics, such as those of meningitis in the Sahel region of Africa, the vaccination starts once the observed number of cases exceeds the level, defined by the WHO. Earlier vaccination could, in principle, prevent more cases and thus reduce the burden of disease, but it could also be unnecessary or of the wrong type. Additional information, such as seasonal patterns, spatial relationship and correlation with natural phenomena, e.g., dust storms, may provide better information and ultimately lead to more efficient decision making. Acting now vs. waiting for more information is another interesting aspect to be studied.
Brainstorming (as of February 2008).

Over the next decade, a Global Earth Observation System of Systems (GEOSS) will revolutionize our understanding of the Earth and how it works, producing societal benefits through more coordinated observations, better data management, increased data sharing and timely applications.
