Measuring Stockpile and Earthwork Volumes with a Drone

1 min read By TOPSCAN

Why a drone beats walking the pile

A single flight captures the whole surface of a stockpile, a quarry face or an excavation. Nobody has to climb unstable slopes, and the result is not built from a few selected profiles but from millions of measured points.

How the volume is calculated

The survey produces a surface model. Volume is the space between that surface and a reference base, which is defined from the surrounding ground or from an earlier survey of the same site.

  • Base surface: the reference that every value is measured against
  • Fill and cut: material above and below the base, reported separately
  • Tolerance: the uncertainty stated next to every volume

Getting numbers you can repeat

A volume is only useful for comparison if every survey uses the same coordinate system, the same base and the same method. Wet ground, vegetation and loose edges can shift a result, so we record the conditions of every flight.

Compare surveys with each other, not with an estimate by eye.

What you receive

Typically a volume statement in PDF or XLSX, contour lines in DXF and an orthophoto of the site. Processing usually takes one to three days, depending on the size of the area.

Project Start

Request a Free Test Flight

We will survey a test area (up to 0.5 ha) of your current project free of charge. You will receive a point cloud or an orthomosaic to verify the data quality in your own CAD software before the project starts.

  • Response within one business day
  • Flight coordination accounting for airspace
  • Sample data in a format that fits your software
