Volumetric Surveys

For landfill and quarry operators, understanding the movement and remaining capacity of material is central to safe and compliant site management. Volumetric surveys turn surface changes into measurable and verifiable data that reveal how airspace, waste or extraction areas are evolving over time. The results guide practical decisions on planning, rehabilitation and daily operations. 

Landair Surveys applies proven ground, drone and aerial techniques to capture accurate, repeatable data that stand up to audit and analysis. Each survey aligns with previous datasets, building a consistent record that helps you see trends clearly and report with confidence. 

Why volumetric surveys matter

Knowing exactly how much space has been filled (or how much remains) underpins every operational and compliance decision on a landfill or quarry site. Volumetric surveys are essential for:

  • Tracking airspace and material volumes – Quantify consumed and remaining capacity.
  • Supporting environmental and licence reporting – Supply verifiable data to regulators.
  • Guiding operational planning – Optimise haul routes, lift sequencing and cell development.
  • Improving financial forecasting – Base royalties, charges or future works on measurable quantities.
  • Reducing safety risks – Limit manual measurements in unstable or restricted areas.

How we capture volumetric data

Landair uses a mix of ground-based GPS, 3D laser scanning and RPA (drone) method, selecting the most efficient and accurate approach for each site. Whichever technique is used, our survey data is processed into accurate digital surface models for volume analysis.

Ground surveys

GNSS receivers and total stations capture the tops, toes and grades of stockpiles or waste cells to millimetre accuracy. Ground methods are viable in all weather and are ideal for small or complex areas.

RPA surveys

Drone flights rapidly map large or hazardous zones with centimetre-level precision. They’re ideal for regular airspace monitoring and stockpile assessments where access is limited.

Aerial photogrammetry

For very large quarries or regional landfill networks, crewed aerial capture delivers wide-area coverage in a single sortie.
