Deliverables
What you get back
Orthomosaic
A true-scale, measurable map image.
More
Distortion-corrected, georeferenced imagery for measuring distances and areas. Typically delivered as GeoTIFF.
Point cloud
Measured 3D points.
More
From lidar or photogrammetry. DJI Terra exports PNTS, LAS, PLY, PCD and S3MB; Wingtra software exports LAS or CSV.
Profiles & sections
Cross-sections along a line.
More
Cut profiles along a road, rail or pipe centerline from the surface model.
DSM / DTM
Surface and bare-earth models.
More
The DSM includes buildings and canopy. The DTM is ground only, built from ground-classified points.
3D mesh
A textured 3D model.
More
Built from nadir and oblique imagery. Good for reviews and stakeholder updates.
Inspection images
Close-ups tied to location.
More
Geotagged photos and zoom frames organized by structure or route.

- Warranty help: we coordinate manufacturer service for the rest of your kit.
Can a drone inspect a bridge?
It captures imagery for a qualified inspector to review. It doesn’t replace the inspection program.
Fixed-wing or multirotor for corridors?
Fixed-wing VTOL like WingtraRAY covers long corridors. A multirotor is better near structures and in tight spaces.
Can we fly over traffic or tracks?
Only within FAA rules and the owner’s access and safety requirements. Plan routes to limit exposure.
What accuracy can we expect?
It depends on control and workflow. Manufacturer figures are on each kit card, with sources below.
Do you support agency purchasing?
Yes. Request a quote and tell us your process.
