Mine Monitoring Solutions

Monitor Mines with Outstanding 98% Accuracy from Space
Mine Monitoring Solutions

Mining operations rely on accurate volume calculations, particularly end-of-month calculations, to estimate how much material contractors extracted from the ground, but also to estimate the efficiency of mining methods and machines. Conventional methods, such as laser scanners or plane-based surveying methods tend to not be very accurate, require staff to be on site or are very expensive.

Based on our Pléiades satellite constellation, we are now able to offer highly accurate and cost-effective mine monitoring solutions and automated services for operational mines. The high-resolution (50cm) optical satellite only needs a single stereo pair image to determine extracted volumes reliably and regularly – even in very remote and inaccessible areas. Costs and risk can be substantially minimised since staff do not have to be on site to measure volumes. Our solutions cover two areas – Change Detection Services as well as Volumetric Calculation Solutions, which are specifically developed for mines.

Change Detection Service

Our constellation now allows you to track changes over your mines, keeping you aware of movements and activities in your areas of extraction. We deliver the information in a comprehensive change detection analysis report online - straight to your desktop.

Volumetric Calculation Solution

Using satellite-based solutions provides a highly cost-effective route to calculate volumes, which benefit from daily revisit capacities of satellites and the fast acquisition of most up-to-date images – no matter where your mine is located.

We can now enable you to estimate piles, stack, earth moving volumes by using our Pléiades 50cm products .

3 Easy Steps to Assess:


Task the satellites and acquire data to:

  • monitor simple stacks: 1 single Pléiades acquisition is enough
  • monitor complex and changing stacks: several Pléiades stereo or tristereo acquisitions are necessary
    • first assessment of stacks with the first acquisition
    • further acquisitions to determine and measure the changes in volumes

Extract the Information to:

  • estimate precise volume of any pile of material above ground
  • estimate volume of added or removed material since last revisit

Deliver the Information: Report Analysis

  • JPG report of the zone showing all studied pile contours with ID and zoomed snapshot
  • Excel sheet with estimated volume of all studied piles (same file incremented at each revisit)
  • KMZ vector of pile contours, with attributes of date and estimated volume


Your Benefits:


  • Cost-efficient – avoids the need to assess on-site
  • No security risk for staff
  • Suitable for inaccessible or restricted areas
  • Reliability and accuracy of the satellite imagery
    • Moving 1m³ can cost up to €5
    • Using paper maps and ground surveying has an error rate of up to 20%
    • First studies done for Monitor Stack showed an error rate of <2%, the lowest error rate with land surveyors is 5%
  • Revisit acquisition to follow up the site


Our Commitment:


  • Delivery within 3 days after acquisition
  • Before proposal: systematic feasibility study by our monitoring team (acquisition, photo-interpretation)
  • After 1st delivery: validation by the client of the outlined contours of piles
  • In case of clouds or no acquisition: attempt recredited for the next revisit window
