Surveying for Mining & Development

Mine Site Surveying

User-ready data for mine and tailings management

Open pit mines and tailings facilities are in a constant state of change. Engineers have a continual need for accurate elevation survey data to manage these dynamic sites safely and responsibly.

PhotoSat’s Mine Site Surveying ensures engineers get reliable, robust, and time-stamped survey data for the entire active area, without the need for site access.

Key applications:

Mine site operations
Volume reconciliation and reporting
Short-, mid-, and long-range planning
Tailings facility management

Elevation grid formats:

File Format(s): ASCII, CSV, DWG, DXF, ECW, ERS, LAS, TIF, and XML.

Thinned Grid formats are available to reduce file size for projects over low-grade slopes.
