Inside stockpile intelligence
See the pile.
Understand the quantity.
Follow the transformation from a physical stockpile to a quantity with a clear, reviewable basis.
01 / Capture
Start with the shape.
Overlapping field images or laser observations build the surface. Coverage and a reliable position reference come first.

Give every pile a boundary.
Separate the material from roads, equipment and neighbouring piles. Review the toe before calculating the volume.

- Capture. Overlapping field images or laser observations build the surface. Coverage and a reliable position reference come first.
- Boundary. Separate the material from roads, equipment and neighbouring piles. Review the toe before calculating the volume.
- Volume. Lift the surface to see the relationship: volume is the space between the reconstructed pile and its agreed reference base.
- Material. Density and moisture come from suitable material testing or documented inputs. Change the examples to see their influence.
- Inventory. Connect geometry, material inputs and the calculation in one reviewable record. Keep the original measurements and assumptions together.
This teaching example uses 24,800 m³ and as-received bulk density in tonnes per cubic metre. As-received mass = volume × density. Dry-solids mass = as-received mass × (1 − wet-basis moisture fraction). Outputs are rounded to whole tonnes. A dry-basis density or dry-basis moisture value requires a different calculation basis. Actual materials may vary across a pile.
The reconstructed surface and reference base must share an appropriate position and height reference. The visible front toe is traced for this illustration; the far-side footprint is an explanatory assumption. Occluded boundaries, base assumptions and data quality affect the result. The raised photographic cutout explains the relationship and is not a measured 3D model.

One place to return to.
Operations and finance can start from the same selected visit and pile record.
From site to review
An agreed basis.
A repeatable process.
Set a repeatable capture and reporting cycle around inventory close. Keep the yard definitions and calculation method consistent between visits.
Define the scope.
Identify piles, materials, ground control and the reference base. Plan around stock movement and record the source and date of density values.
Measure the shape.
Capture the yard, process the surface, check control and calculate each pile’s volume. Convert to estimated tonnes using the documented material basis.
Make it usable.
Deliver pile-level records, a stock statement and the agreed surface archive. Review period changes alongside weighbridge or other available site records.
Before the first capture
A few details
worth getting right.
Does a drone measure tonnes directly?
Field capture measures geometry. Estimated tonnage is calculated from volume and an applicable material density. Density, moisture and the chosen base can affect the result, so the calculation basis should accompany it.
Can one visit be compared with another?
Yes, when the measurements use compatible pile definitions, reference surfaces and measurement assumptions. Define the comparison before capture so that changes can be interpreted meaningfully.
What should we share to scope a measurement programme?
A site location, approximate yard area, material types, access constraints and your preferred capture timing. If you have prior measurements, a pile register or density information, it helps establish the basis.
What will the final output include?
A typical scope includes pile-level volume records, density-based tonnage, a stock statement and the supporting site or surface output. Agree report formats, quality records and comparison periods with the project team. Density and moisture inputs must have a documented basis.
Prepare for the measurement programme
A stronger brief.
A more useful stock statement.
Bring the people who use the result into the scope: site operations, field specialists, stores and finance may each need a different view of the same inventory.
The site and materials
Share the yard layout, access constraints, material categories, approximate pile count and the periods you want to compare. Identify moving equipment and any stock that will change during capture.
The measurement basis
Agree ground control, pile boundaries and the original ground or reference-base method. Record the source and date of density values used for tonnage estimates.
The reporting need
Define the breakdown by pile, material and yard, plus the review and sign-off process. Comparisons should use compatible methods, dates and material assumptions.
