Site feasibility, before due diligence closes — measured, not assumed.

Development feasibility is a numbers exercise built on terrain assumptions. Drone LiDAR replaces the assumptions with a real, captured surface — driving slope analysis, buildable area, indicative yield and cut/fill budgets that survive the planning and engineering scrutiny they need to.

From a parcel to a yield estimate, in three views.

Toggle between slope classification, buildable area and indicative lot yield. The underlying DTM is the same — the town planner's slope map, the architect's constraint mask, and the development manager's yield estimate all come from one capture.

The problem

Why most feasibility studies start from terrain guesswork.

Development decisions live or die on early-stage assumptions. But the terrain layer underneath those assumptions — slope, drainage, ground levels, vegetation, easements — is usually inferred from contour mapping that's years old, sparsely sampled, or simply unavailable for the parcel.

  • 01 · Public contours are coarse and dated

    Open contour mapping at 1 m or 2 m intervals smooths over the swales, low points and minor ridges that drive lot grading and drainage decisions. On a real parcel they routinely move buildable area boundaries by metres.

  • 02 · Visual site walks miss the maths

    Walking a parcel gives a feel, not a number. Site slope, cut/fill budget, drainage extent and indicative yield can&apos;t be defended from a few photos and a gut estimate — even by experienced eyes.

  • 03 · Ground survey blows out the DD timeline

    Commissioning a traditional ground survey to feasibility-grade detail can add weeks to a due-diligence window. The result: feasibility numbers locked in before the survey returns, then quietly revised when reality lands.

  • 04 · Yield assumptions chain into the price

    Indicative lot count, platform heights, cut/fill budget and drainage works all feed the offer price. A 10% yield miss or a 50 mm platform error multiplies through the entire development budget.

Why LiDAR

One LiDAR capture replaces every terrain assumption with a real measurement.

A single drone capture early in due diligence produces the bare- earth DTM that drives every downstream feasibility view — slope classification, buildable area, indicative yield, cut/fill budgets, drainage extent and constraint maps. Captured in hours, delivered in days, defensible at planning.

  • Whole-of-parcel coverage

    100% of the site captured at sub-metre resolution. No sampled traverses, no interpolation between station points, no missed low spots.

  • Slope analysis at the cell level

    Slope class raster (5-band) generated directly from the DTM. Buildability bands match the thresholds town planners, architects and stormwater engineers use day to day.

  • Constraint mapping built in

    Drainage lines, low points, easement strips and steep batters identified and excluded from buildable area automatically — the constraint mask the architect actually needs.

  • Indicative yield, defensibly

    Subdivision overlays drop onto the constraint mask with per-lot cut/fill, slope and buildability scoring. Yield estimates become a measurement, not an aspirational number.

  • Vegetation captured too

    Canopy structure, heritage trees, retention candidates and clearing burden all classified from the same capture — important for planning approvals and lot rationale.

  • Captured before bid lock-in

    Flight and processing typically inside a week — fast enough to inform the offer price rather than chase it. Often the difference between winning a deal and walking away.

Workflow

A typical property feasibility capture, end to end.

  1. 01
    Scope

    Parcel extent, planning controls, drainage context and deliverable list confirmed with development manager / consultant team.

  2. 02
    Capture

    Single-mobilisation drone flight covering the parcel at multi-return density. CASA permits, neighbour notifications, control set if required.

  3. 03
    Process & derive

    Bare-earth classification, slope raster, buildable mask, indicative yield analysis, vegetation inventory. Independent QA pass.

  4. 04
    Deliver

    Feasibility-ready pack landed with development team and consultants inside the DD window — typically a week from go-ahead.
