Photogrammetry
Structure-from-motion processing that converts thousands of aerial frames into dense point clouds, textured meshes and true-scale measurements you can interrogate in any CAD or GIS package.
- Image overlap
- 80% front / 70% side
- Point density
- 150-600 pts/m2
- GSD range
- 0.8-3 cm/px
- Output formats
- LAS, OBJ, PLY, GeoTIFF
What it is
Turning overlapping imagery into measurable 3D geometry
Photogrammetry is the engine underneath most of our deliverables. By matching millions of common features across overlapping photographs, the software reconstructs both the camera positions and the three-dimensional shape of everything they saw.
Quality depends far more on capture discipline than on software. We fly with fixed exposure, calibrated lenses, high overlap and cross-hatch patterns over complex geometry, and we add oblique passes wherever vertical faces matter - facades, cut slopes, stockpile walls and structures.
For clients who already have imagery, we offer processing as a standalone service. Send us your raw frames and flight logs and we will run the full pipeline, quality-check the block adjustment and deliver the same validated outputs.
What you receive
- Dense RGB point cloud (LAS/LAZ, up to 600 points per m2)
- Textured 3D mesh (OBJ, FBX, glTF)
- True-orthophoto with building lean corrected
- DSM and DTM raster grids
- Camera calibration and bundle adjustment report
- Measurement-ready web viewer link

How we deliver it
Our photogrammetry workflow
Each step exists because skipping it shows up later as an error somebody else has to find.
Capture design
We compute the GSD your accuracy target demands, then derive flight altitude, overlap, speed and shutter settings from it rather than the other way round.
Redundant acquisition
Nadir grid plus oblique passes at 45 degrees, with cross-hatch coverage over structures and steep terrain.
Block adjustment
Aerial triangulation with GCP constraints, outlier rejection and a documented reprojection error, typically under 0.8 pixels.
Dense reconstruction
Multi-view stereo densification, noise filtering and ground/non-ground classification.
Validation
Check points held out of the adjustment are measured in the final model and reported as RMSE in all three axes.
Where it is used
Typical applications
- As-built documentation of structures and industrial plant
- Heritage and architectural recording at millimetre detail
- Slope stability and rockface geometry monitoring
- Accident and incident scene reconstruction
- Input geometry for BIM and digital twin workflows

Ground Sampling Distance is the real-world size of one pixel. A 2 cm GSD means each pixel covers 2 cm on the ground. As a rule of thumb your achievable accuracy is 1-3x the GSD, so the deliverable specification should drive the flight altitude.
