Geomatica now features leading edge, completely redesigned wizard based Atmospheric Correction workflows that will allow users to automatically detect cloud and haze within imagery which will make producing seamless mosaics in cloud plagued areas more intuitive. Automated metadata extraction will greatly improve the speed and accuracy of your workflow.
