15cm Accuracy Topography for Oil Sands

PhotoSat’s 15cm accuracy satellite topographic data enhances traditional ground surveying and reduces field crew costs in all phases of oil sands mining.

We survey all 7 of the Alberta oil sands mines, some on a bi-weekly or monthly basis. Mining and tailings engineers are using our satellite surveys for:

  • Highly accurate mapping of sand dumps.
  • Mapping and monitoring tailings beaches and dykes, eliminating ground survey crew exposure to hazards and reducing water usage. Accurate measuring of the clay thickness in mature fine tailings cells in 15cm intervals.
  • Improving volume calculations in pits, waste dumps, and stockpiles.
  • Mine site toes and crests data for daily dispatch maps and other processes.
  • High accuracy volume measurement of windrows.

Experience

PhotoSat has completed over 900 satellite mapping projects globally since 2004:

Highest accuracy elevation data

PhotoSat produces highly accurate 1m elevation grids (DEMs) with 50cm or 1m contours from satellite photos using our geophysical processing technology. We have invented a process that produces detailed surface topography from stereo satellite photos with 4 times the accuracy of conventional satellite mapping. Our accuracies have been proven and reports are available on the Satellite surveying accuracy studies page.

We achieve 15cm elevation accuracy in oil sands mines using a proprietary set of algorithms that were derived from oil and gas seismic processing. Find out more about our unique process on the Technology page.

PhotoSat satellite surveying benefits:

  • Engineering accuracy for oil sands engineering projects.
  • Improves safety for field crews in hazardous areas.
  • Fast delivery: usually within 8 days of satellite data acquisition.
  • Cost-effective alternative to GPS surveying and aerial LiDAR.
  • Custom formats and projections.
