Decision tool · ~90 seconds

Which survey method fits this project?

LiDAR, photogrammetry, traditional ground survey and hybrid workflows each solve different problems. The most expensive mistake in spatial capture is matching the wrong method to the deliverable. Answer six questions and we'll recommend the approach we'd actually use on your project — with the trade-offs called out honestly.

Six questions · Roughly 90 seconds
Decision tool

Should this project use LiDAR, photogrammetry, traditional survey — or a hybrid workflow?

The wrong method costs weeks and re-flies. The right method delivers a single, validated capture that downstream design, earthworks and reporting can run on without question. Six questions, real engineering weighting, no email gate.

  • Vegetation cover and bare-earth requirement
  • Vertical accuracy needed for the deliverable
  • Site size and project timeframe
  • CAD/BIM vs visual deliverable mix
Methods scored
  • LiDAR
    Active laser scanning. Centimetre-precise terrain — even under canopy.
  • Photogrammetry
    Reconstruct a 3D surface from overlapping aerial imagery.
  • Traditional
    Total station / RTK GNSS by a licensed surveyor. The legal benchmark.
  • Hybrid
    LiDAR for geometry, camera for context. Both passes, one capture.
How we weight the answers

The honest version of method selection — without the sales pitch.

We run LiDAR because it's the right tool for most of the work we do. That doesn't make it the right tool for every project. Here's how we actually think about method selection on a scoping call.

  • 01
    Vegetation is the first filter

    Photogrammetry can only model what its cameras can see. Any project requiring bare-earth surface under canopy needs LiDAR or a hybrid workflow — there is no photogrammetric workaround.

  • 02
    Accuracy budget drives method

    Engineering tolerances of ±20 mm push toward LiDAR or ground survey. Planning-grade visuals at ±150 mm open up photogrammetry as a cost-effective option.

  • 03
    Site economics shift with size

    Traditional ground survey is unbeatable on small lots and uneconomical on large corridors. Aerial methods invert that curve. The crossover is usually 5–10 ha for detail capture.

  • 04
    Deliverables determine the chain

    CAD/BIM design surfaces flow naturally from a classified LiDAR cloud. Photoreal orthomosaics flow naturally from photogrammetry. Most engineering projects want both — that's what hybrid is for.
