Dr. Alain Gachet founded Radar Technologies International (RTI) in 1999 to use satellite generated data to identify probable locations of precious metals and during its use found it could also detect water. The system developed with this data, WATEX, uses about 80 percent of its data inputs from publicly available NASA information. This free information allowed RTI to develop the WATEX system to successfully locate water sources, such as in 2004 at refugee camps during the War in Darfur.
