📊 Ever wondered how quarries and recycling yards know exactly how much material they have? This is how we do it. ⬇️
We just completed a LiDAR drone survey at a Christchurch recycling facility — measuring five huge stockpiles of different materials to get accurate volume and weight figures. All up, over 7,149 cubic metres of material, measured in a single flight.
The colourful image is the live LiDAR scan being built in real time on our remote screen as the drone flies over the site. Every dot is a laser return — millions of them — building a precise 3D map of everything below. We can then measure the exact volume of each stockpile from that data, accurate to within 2%.
The old way of doing this? Someone walking around with a measuring wheel, someone else climbing the pile. Slow, rough, and frankly a bit dodgy from a safety perspective.
The drone way? One flight. Precise data. Full report within a day.
Got stockpiles, earthworks, or bulk material you need measured? We do this all over New Zealand.

Drop a 👍 if you’ve seen drone tech like this before — it still blows our minds every time! 😄
