Open pit mines monitoring

detecting changes in open pit mining

Separate activity monitoring was conducted for various open pit mines in the US. Different technologies and analytical approaches were used by our experienced team of data scientists based on the goals and objectives of our clients.

For one group, we used interferograms, allowing us to see subsidence. For the second group, we used displacement map technology. For the third and final group, we used both.
