Photogrammetry

Drone data you can measure against.

We fly the site, tie every pass to survey-grade GNSS control, and process it into point clouds, surfaces, and CAD-ready linework. Not pretty pictures. Measurable ground.

The workflow

Capture, process, deliver.

The same three moves every job runs on, tied to control from the first pass so the data holds up.

1
Capture

Fly to control

Planned drone flights with ground control tied to survey-grade GNSS, so scale and position are locked in.

2
Process

Build the model

Imagery becomes a dense point cloud, then surfaces, contours, orthomosaics, and volumes, checked against control.

3
Deliver

Hand off clean

CAD-ready linework and surfaces in the format your crew works in, ready to drop into the project.

→ Control first: every deliverable traces back to survey-grade GNSS.

What we deliver

From flight line to final file.

Pick the deliverables the project needs. We can hand back one clean file or the full set.

  • Dense point clouds
  • Digital surface + terrain models
  • Orthomosaics
  • Contours and breaklines
  • Volumes and cut/fill
  • CAD-ready linework
Where it fits

Built for the jobs surveyors actually run.

01

Highway & corridor

Long, linear mapping where topo by foot would burn days and lane closures cost money.

02

Pipeline & utility

Route survey and existing-condition capture across ground that is slow to walk.

03

Petrochemical & industrial

Dense point clouds of complex sites, captured fast and safely from the air.

04

Sites & earthwork

Surfaces and volumes for grading, stockpiles, and as-built checks against design.
