ERDAS Inc., Atlanta, Ga., and Environmental Systems Research Institute Inc., Redlands, Calif., donated more than $1,000,000 worth of software to the leading Costa Rican universities at the Seventh Annual Latin American User Conference. The software is used to advance science and engineering courses and help train students on using geographic imaging tools to solve complex spatial problems and protect valuable resources. In addition, the software will help start a national project using high-resolution satellite imagery and digital photography to create 3-D graphics of the country’s terrain and resources.
