deliverables
TechnologyDrone work is a data business that happens to involve aircraft. The flying is the easy, visible part; the value is in what comes out of the processing pipeline afterwards and whether the numbers in it can be trusted.
That trust comes from ground control. A survey flown without surveyed control points produces imagery that looks right and measures wrong, sometimes by metres. Every mapping job here is flown against established control, and the deliverable arrives in the coordinate system your team already works in rather than one you have to transform out of.
The repeat work is where it earns its keep. Stockpile volumes measured monthly with the same flight plan and the same control are comparable month over month, which is what turns a survey into a management tool instead of a one-off document.
Capability
What this division does
Mapping & orthomosaic
Georeferenced imagery at survey resolution, delivered in the coordinate system your team already works in.
Topographic survey
Point clouds and digital elevation models for earthworks planning and drainage design.
Volumetrics
Stockpile and cut-fill measurement, repeatable month over month so the numbers are comparable.
Progress capture
Scheduled overflights that give a construction record nobody has to be on site to collect.
Audience
Who commissions this
Construction firms tracking site progress and earthworks
Quarries and yards measuring stockpile volumes
Surveyors needing coverage faster than ground methods allow
Planners and developers assessing a site before purchase

Deliverables
What you actually receive
Named artefacts rather than adjectives: the things that exist at the end, and can be checked against this list.
Georeferenced orthomosaic
A single measurable image of the site at survey resolution, tied to real coordinates.
Digital elevation model
Terrain and surface models for drainage, earthworks and cut-fill planning.
Volumetric report
Stockpile and cut-fill quantities, with the method stated so the numbers can be audited.
Point cloud and 3D mesh
The full captured dataset, delivered in an exchange format your software reads.

Questions
Asked before commissioning
The questions that come up on nearly every enquiry, answered here so the first call can start further along.
With surveyed ground control, 2 to 3 cm horizontally and slightly worse vertically is a realistic expectation for typical site work. Without ground control, the imagery may look identical and be metres out. Anyone quoting survey accuracy without mentioning control is quoting the easy half of the job.
Yes. Airspace authorisation, notification and the operational paperwork are part of the engagement in both markets, and are settled before a scheduled flight rather than on the day.
Wind above the airframe limit, rain, and low cloud that would sit between the camera and the ground. Flights get rescheduled rather than flown badly, since a compromised capture costs more to work around than a lost morning.
If the cadence is high enough, that usually works out cheaper. Survey airframes and RTK modules are sold in Shop, and Education & Training runs the mapping course that covers flight planning, control and deliverable QA.
