The problem

Ground methods do not scale to a site.

Earthworks and corridor projects need coverage, not points. Walking a site with traditional instruments gives a sparse sample of a surface that is changing weekly, and the gap between survey visits is where volume disputes and quantity disagreements live.

Flying the site captures the whole surface at once. Volumes come from a measured model rather than an interpolation between spot heights, and repeating the flight makes change over time straightforward to quantify.

What we do

What an aerial capture produces.

Terrain models

DSM and DTM surfaces, contours and levels across the whole site.

Stockpile volumes

Volumes computed from a measured surface, repeatable between visits.

Corridor capture

Linear assets and corridors as continuous point clouds, ground or air.

How it runs

Fly it, then fly it again.

The value compounds with repetition. A baseline flight establishes the surface, and each subsequent flight measures what moved. Permit lead time is built into the quote, so a monitoring cadence can be planned against the programme rather than improvised.

About land survey
What Volumet provides
  • Airspace screening, CAAS permitting and flight planning
  • Aerial and ground capture by our team
  • Terrain models, volumes and contour deliverables
  • Scoped quote within one business day
What Volumet does not claim
  • Cadastral or boundary survey, which is the statutory preserve of a Registered Surveyor, and which we refer
  • PE-endorsed structural certification: we document condition, a Professional Engineer signs off adequacy
  • QP submission sign-off: we produce the drawings and models, your Qualified Person submits them
  • Guaranteed absolute survey-grade accuracy: around 1 cm relative at device level, and the real number depends on the whole chain

Aerial capture, answered.

Do you handle the CAAS permits?
Yes. Airspace screening, CAAS permitting, flight planning and site-owner consent are part of the engagement. Permit lead time is real and it is built into the quote rather than discovered later.
What if the site cannot be flown?
Not every site can be. Restricted airspace, proximity to aerodromes and site-owner refusal all rule out flight. Where that happens we capture from the ground with long-range SLAM instead, and say so before you commit.
How accurate are the volumes?
Volumes are computed from a measured surface rather than interpolated between spot heights, which is generally the more reliable method. Absolute accuracy depends on control, flight parameters and processing, and we state the expected figure for your site in the quote.
Is this cadastral survey?
No. Legal boundaries, title and strata subdivision are the statutory preserve of a Registered Surveyor. We do topographic and volumetric work, and refer boundary survey rather than attempting it.
