Rapid changes in site areas, including stockpiles, tailings, water bodies, and waste dumps, create challenges for engineers and operators. On-site survey methods are not always available, and infrequent data reduces the ability to quickly identify operational risks or deviations from operational plans.
PhotoSat provides high-accuracy, high-frequency satellite surveys for small to mid-sized operational areas, ensuring reliable and timely data without the need for on-site access.
Highlights:
Custom mine grid coverage (0–10 km² within 25+ km² capture)
Our standard set of deliverables include orthophotos, elevation grids, and contours, providing accurate, georeferenced information for site analysis and ongoing measurement.
