Automated Aerial Intelligence for Aggregates

The Kespry automated drone system is a fast and simple way to measure stockpile volumes. Kespry UAVs are fully automated. No pilot training or joystick flight skills are required to fly. The drone takes off, flies, and lands autonomously. The aerial data captured is automatically processed into accurate mining maps and models that your team can access and work with from anywhere using the online Kespry Cloud.


Less than 30 minutes to fly 150 acres


Millions of data points in each 3D model


Less than 1 minute to measure each stockpile

"This is a tool that as a global aggregates business we see as definitely scalable and applicable in many countries and regions allowing us to harmonise and standardise on practices and process worldwide."

Neil Wells, Head of Land and Minerals • HeidelbergCement

Mine Planning

Survey-grade accuracy from the Kespry 2s system provides reliable data used in mine planning applications. Customers use Kespry for blasting operations, comparing volume measurements from stripping, performing takeoffs, mine reclamation work, or even to estimate levels of reserves.

In the Kespry Cloud, customers view and download contours, point cloud data and each of the high-resolution 2D mine maps and 3D quarry models for AutoCAD and other third-party software platforms. The Kespry team are continually adding new tools to help mining companies save time and money.
