Mines and quarry management

Sentinel provides autonomous, rapid and economical technical solutions for the management and operation of quarries or mines, by carrying out aerial maps and precise topographic surveys, to obtain 2D or 3D modeling of the quarry or mine.


This technique eliminates the risks associated with the movement of on-site personnel, surveyors or other technicians, no longer needing to travel to inspect or carry out surveys in the field.


Sentinel produces topographic plans, analyzes the data produced by calculating an extracted volume, or a high precision stock cubature.
