Drone Orthomosaic
We fly a programmed photogrammetric mission over your site with high image overlap and GNSS-RTK ground control points, then process the imagery into a geometrically corrected, coordinate-referenced high-resolution orthomosaic GeoTIFF — plus a DSM surface model, a DTM terrain model, contour lines, and cut-and-fill volumes where needed. Hundreds of acres per single mission at 2–5 cm/px ground resolution: data ready for design, monitoring, and calculation.

The problem we solve
Surveying large or rough sites the traditional way is slow, costly, and sometimes unsafe. UAVs give you a geometrically corrected aerial image covering hundreds of acres in days — accurate enough for design and quantity take-off.
Who needs this service
Contractors, developers, energy and mining firms, and anyone needing fast, accurate aerial coverage of large sites.
When you need this service
- To survey large or hard-to-access sites
- To monitor construction progress from the air
- To compute cut-and-fill volumes over large areas
How we execute
- 1
Plan the flight path and distribute ground control points
- 2
Fly the mission and capture high-overlap imagery
- 3
Photogrammetric processing and model reconstruction
- 4
Produce the orthomosaic + DSM/DTM and run QA
What we need from you
- Boundary of the area to fly
- Flight permits where required
- Ground control points if available
What you receive
- High-resolution orthomosaic GeoTIFF
- Digital surface (DSM) and terrain (DTM) models
- Contour lines and volume calculations
- Flight and accuracy report
Equipment & methodology
We equip this service from our owned fleet of 90 instruments:
Survey drones
UAV photogrammetry and LiDAR for orthomosaics, topographic mapping, and asset inspection.
We own and operate our field fleet — our site shots carry the “From our field work” chip, alongside class-reference photos.

Frequently asked
How accurate is the orthomosaic?+
Ground resolution reaches 2–5 cm per pixel depending on flight altitude, with centimeter positional accuracy when GNSS-RTK ground control points are used.
Do you handle flight permits?+
We advise on the requirements and coordinate the necessary permits before the mission, based on the project location.
How much does a drone orthomosaic cost?+
It depends on scope: coverage area, number of missions (one-off or periodic monitoring), target ground resolution, ground-control requirements, and permits. On large areas the per-acre cost drops noticeably compared with ground surveying. Tell us the site boundary and purpose and we will send a detailed quote.
How often can flights be repeated for progress monitoring?+
Monthly or weekly monitoring programs are common among our clients; each mission produces an orthomosaic comparable to the previous one (coverage, elevations, volumes), so progress is measured in numbers, not impressions, and data accumulates into a documented project time archive.
What formats do you deliver, and how do I use them in my software?+
The orthomosaic and DSM/DTM models are delivered as GeoTIFF files that open directly in QGIS, ArcGIS, and AutoCAD Civil 3D; contours come as DWG/DXF, with a KMZ for quick Google Earth preview and a CSV point table. All files are referenced to the agreed coordinate system and drop straight onto your drawings.

Our guarantees to you
We take the risk off your project — so you can commit with confidence.
Accuracy guarantee
If a deliverable misses the agreed accuracy spec, we re-survey and correct it at no extra cost.
On-time commitment
We agree the delivery schedule up front and keep you updated at every stage until it's met.
Full confidentiality
Every engagement is covered by an NDA. Your data and drawings are never shared.
You own the files
You receive the editable source files (DWG, DXF and more) — full ownership, no lock-in.
