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.
