Globally, more than 12,000 tailings facilities exist, many without survey records from construction or deposition. By applying deep learning technology to archived satellite photos, PhotoSat has produced an engineering-quality survey record for a tailings facility, from the mid-1960s to the present day.
In our tailing history case study, PhotoSat created a full survey record of the TSF construction and deposition for the southern TSF for every year throughout its operational life.

Based in Vancouver, BC, Canada, PhotoSat was founded in 1993 on a mission to provide better data for better decisions.
PhotoSat uses data processing with proprietary deep learning algorithms to produce engineering-grade survey data from stereo satellite photos.
We specialize in satellite-based elevation surveying for operating mines, tailings facilities, and earthworks construction projects. We have completed more than 1,300 projects in over 75 countries.
