Stockpile Volumetrics Explained
From flight planning to final volume report, how we deliver accurate stockpile measurements
Drone Services Ireland captures hundreds of overlapping aerial photographs of your site, processed into a dense 3D point cloud and digital surface model. Volume is calculated by defining a base plane beneath each stockpile and computing the material above that surface.
A drone stockpile survey captures hundreds of overlapping aerial photographs from multiple angles. These images are processed with photogrammetric software to generate a dense 3D point cloud and a digital surface model (DSM) of the stockpiles and surrounding terrain.
Volume is calculated by defining a base plane beneath each stockpile and computing the volume of material above that surface. The base plane can be set to match the existing ground level, a flat reference plane, or a design surface, depending on your requirements. Both cut and fill volumes can be calculated from the same dataset.
Ground control points (GCPs) are placed and surveyed across the site before the flight. For recurring surveys, we establish permanent GCP positions to ensure consistency between visits. When permanent markers are not practical, we use at least five GCPs plus independent checkpoints.
Flight planning is configured for the site size, stockpile height, and required ground sampling distance. We typically fly at 50 to 80 metres AGL with 75% frontal and 65% side overlap. For tall or steep stockpiles, we add oblique flight passes to capture the sides where nadir-only coverage would create data gaps.
Data capture uses our DJI Matrice 300 RTK with the Zenmuse P1 (45 MP full-frame camera) for maximum resolution. RTK positioning provides centimetre-level accuracy in real time, with PPK available as backup.
With properly surveyed GCPs and RTK/PPK drone positioning, we achieve ±5cm positional accuracy on the surface model. For a typical quarry stockpile of 5,000 cubic metres, this corresponds to a volumetric accuracy of ±2% or better.
This compares favourably with traditional GPS rover surveys, which typically capture 50 to 100 spot measurements per stockpile and rely on interpolation. A drone survey captures thousands of surface measurements, yielding a far more complete and accurate representation of the pile geometry.
For recurring surveys, we use the same ground control network, flight parameters, and processing methodology for each visit, ensuring volume changes reflect real material movement rather than measurement variability.
When stockpiles are surrounded by vegetation, or the survey extends beyond the stockyard, we use drone LiDAR instead of, or in addition to, photogrammetry. Our DJI Zenmuse L2 captures up to 1,200,000 points per second and penetrates vegetation to generate bare-earth terrain models.
LiDAR also performs well on dark or uniform-coloured stockpiles such as coal, peat, or tarmac, where photogrammetry can struggle to generate accurate surface models due to lack of visual texture.
For recurring programmes, we schedule surveys on a monthly, quarterly, or annual cycle to suit your reporting requirements. Permanent GCP positions ensure consistency between visits.
Comparison reports show volume change between survey dates, net material movement, and tonnage estimates based on your supplied material densities. Emergency or short-notice surveys are available, and we have demonstrated the ability to mobilise, capture, process, and deliver results within a single working day.
The drone operates from above the site. No need to halt production, move machinery, or restrict access. No personnel walking on or around unstable stockpiles.

Frequently Asked Questions
With RTK/PPK positioning and properly surveyed ground control points, we achieve volumetric accuracy of ±2% relative to the true value. This is comparable to, or better than, traditional GPS rover methods, which rely on far fewer measurement points and greater interpolation.
Flight time depends on the site size and the number of stockpiles. A typical quarry with 10 to 20 stockpiles can be flown in 30 to 60 minutes. With GCP setup and equipment preparation included, most sites are completed within half a day. Processing and delivery of the volume report typically follow within 24 to 48 hours, though same-day delivery is available for urgent requirements.
No. The drone operates from a safe distance above the site. There is no need to halt production, move machinery, or restrict access. This is one of the key advantages over traditional methods, which require personnel to physically walk on or around stockpiles.
Yes. If you provide the material density (loose or compacted) for each stockpile type, we include tonnage estimates in the volume report. We can also use standard density values for common materials, such as crushed stone, sand, gravel, topsoil, and clay, when specific densities are unavailable.
This depends on your operational and reporting requirements. Quarries typically survey monthly or quarterly to manage inventory. Construction sites may require surveys at key milestones or on a fortnightly cycle during active earthworks. Landfill operators often conduct quarterly or annual surveys for regulatory reporting.
We require dry conditions, moderate wind (below 10 m/s), and reasonable visibility for photogrammetry surveys. Light overcast conditions are actually ideal as they reduce shadows on stockpile surfaces and improve data quality. We monitor forecasts closely and will reschedule if conditions are not suitable for accurate data capture.
