important point here. what is the universe of the possible? when people calculate 1000 year flood, which is the actuarial projection? if you use sixties and seventies data, you get bad risk assessments because the climate is changing. that seems to be a crucial part of this here. all forms of civil engineering and environmental engineering now have to take as the data set, that they calculate risk off of, how much more current set of data and project out forward, to be able to meet the kind of tail risk possibilities that threaten us. >> well, this effort in new orleans, after katrina was actually the first geospatial distributed infrastructure system that was rebuilt and redesign based on risk information that was brand-new. we ask has been used in a lot of other industries.
