TM-01
Land & Environment
Topographic Mapping & Contour Generation
Bare-earth terrain, contours and breaklines over open ground, tied to a distributed control network.
- Ground sampling
- 2.74 cm/px
- Horizontal RMSE
- 1.2 cm
Survey-grade aerial data capture
We fly RTK and PPK survey missions, process the trajectory ourselves, and hand you a checked point cloud, terrain model and orthomosaic with a signed accuracy statement. No black boxes, no rounded numbers.
Service catalogue
Ground sampling distance, achievable RMSE, point density and single-sortie coverage are stated for every service before you commit. If a site cannot hold the figure, we say which one moves and why.
TM-01
Land & Environment
Bare-earth terrain, contours and breaklines over open ground, tied to a distributed control network.
LT-02
Land & Environment
Multi-return scanning that finds the ground where photogrammetry only ever sees leaves.
EV-03
Mining & Quarry
Cut, fill and stock quantities against a design surface or a prior epoch, back inside 48 hours.
MQ-04
Mining & Quarry
Bench geometry, face position and haul road condition on a live pit, flown around the shift.
CI-05
Energy & Utilities
Conductor position, vegetation encroachment and structure condition along linear assets.
AB-06
Civil & Construction
Sub-centimetre verification of what was actually built, against what was actually drawn.
OM-07
Civil & Construction
Radiometrically balanced, properly orthorectified imagery you can measure on, not just look at.
TH-08
Energy & Utilities
Radiometric thermal survey of generation assets, mapped to module position rather than to a video timestamp.
AG-09
Land & Environment
Calibrated five-band reflectance and derived indices, referenced to a panel measured on the day.
CM-10
Land & Environment
Repeat-epoch capture of erosion, accretion and bank retreat with the uncertainty stated per epoch.
BS-11
Civil & Construction
Millimetre-scale imagery of deck, pier and soffit geometry without a closure or a rope team.
GC-12
Civil & Construction
Target networks, checkpoint observation and independent validation of somebody else's survey.
What you receive
Exactly what is included with each service in the catalogue, filterable by sector. If something you need is not on the list, ask — most requests are a scoping conversation, not a limitation.

Every job also ships the raw imagery or raw scanner returns, the processing report and the checkpoint residual table. Coordinate reference system and vertical datum are set from your project spec before the first flight.
How a job runs
You send a boundary, an accuracy class and a delivery format. We check airspace, terrain relief and obstruction, then fix the altitude, overlap and control scheme.
Targets are set and observed on a static base, distributed across the block and across the relief. Thirty per cent are held back as blind checkpoints.
Flown to the planned line spacing with cross-strips at the block ends. Coverage and exposure are verified on site before the crew stands down.
Trajectory processed forward and reverse, bundle adjusted against the marks, cloud classified to ground, vegetation, building and low noise.
Residuals computed on the withheld checkpoints and published as a table. A surveyor signs the accuracy statement — not a script.
