When the call came in from a limestone quarry in Iowa, USA, the situation was dire. A massive fall of ground had occurred underground, rendering approximately 22 acres of active mining area unstable, dangerous, and uncertain.  How to assess the damage without putting anyone at risk? 

That’s when Unmanned Aerial Services (UAS) deployed Emesent’s Hovermap autonomous drone technology. 

Download the case study to find out how UAS mapped over 5 kilometers of underground workings to deliver actionable intelligence within 48hrs of the call.
