Ten pilot sites were selected in the area of Hualgayoc in Cajamarca to be monitored using different remote sensing technologies.
Colquirrumi Tailings No.3, a closed site awaiting closure certificate, will be monitored with Global Navigation Satellite System (GNSS) sensors and Interferometric synthetic aperture radar (InSAR) images. The other height sites, closed or abandoned, will be monitored with InSAR technology.
