unprecedented power and bandwidth to understand and predict the interaction of natural and human processes better.


The intent of this roadmap is not to be prescriptive regarding SDI development and implementation but to identify keys to success on the basis of lessons learned from other SDI implementation efforts. The committee recognizes that there are many feasible ways of implementing an SDI program successfully, but all will require that an SDI program be properly defined, led, and supported. The committee believes that such an effort can be best framed by the phrase “discover and share for the long term”, and it hopes that this phrase can become the mantra for spatial data handling throughout the USGS.
