Survey anywhere in the world with PhotoSat.

Most tailings surveying requires accuracies of better than 20cm in elevation.  The Canadian Oil Sands Innovation Alliance (COSIA) in their 2015 publication, “Guidelines for Tailings Deposit Sampling and Measuring Tools” specify the required accuracy of TSF surveys as follows:

Aerial surveys survey (of the pond hard bottom) should have and accuracy of +/- 15 cm

PhotoSat consistently surveys mine sites to an accuracy better than 15 cm in elevation. This accuracy has been verified by tens of thousands of ground survey points on many mine sites and oil and gas fields.

This PhotoSat mine tailings survey matched the survey checkpoints to a standard deviation (RMSE) of 11 cm 

Independent, auditable, archive of tailings structure construction

Monthly PhotoSat surveying during TSF construction provides an independent, auditable record of the construction history.  This facilitates the engineering design of future TSF expansion. 

15 cm elevation surveying accuracy required for TSF surveys

Waterbody margins can be difficult to impossible to identify on visible spectrum Red Green Blue photos (left image).  They can be clearly defined and mapped using multispectral satellite photos that include infrared bands (right image).
