Stockpile volumes & earthwork.

For a stockpile, drone imagery is processed into a surface that describes the visible material. The volume is calculated between that surface and a defined base within the selected pile boundary. The result depends on all three: the surface, the base and the area included.

For a material yard, the record can support an internal inventory review or help your team discuss how individual piles have changed. An overhead view or model identifies the pile, while the units and base method explain the quantity. Where piles touch or a wall hides an edge, we review whether they can be treated as separate piles.

For earthwork documentation, the question may be how a selected area changed between two visits. A cut-and-fill surface comparison may instead involve an existing surface and a suitable supplied reference. These are different comparisons, and the required inputs should be clear from the start.

The surfaces need compatible units and reference information. An alignment offset can look like a change in ground level, even where no material has moved. We review the available inputs and the checks needed before agreeing to a comparison. If repeat visits are planned, consistent coverage and reference information help make the later results useful.

If you need to review the same yard or work area again, identify the piles and coverage you want to follow. Consistent names, capture dates and units make the records easier to compare. Changes to a pile boundary or reference base should be explained alongside the new result.

Tell us if material is being moved during the planned visit or if some areas are temporarily inaccessible. Site activity and obstructions can affect the capture. A repeat visit is most useful when it records the intended area under conditions that support the comparison.
