Use cases
Survey-grade capture
© DJI
© DJI
Boundary support
Imagery that backs up fieldwork.
Details
- Orthomosaics showing fences, walls and monuments
- Evidence for the surveyor’s analysis
- Not a boundary determination on its own
© DJI
GCP, RTK & PPK
Tie the data to your control.
Details
- RTK corrects positions live; PPK corrects them after the flight
- Ground control points tie the model to your coordinate system
- D-RTK 3 base station and Hoodman GCP kits available

Ground under canopy
Lidar finds the ground through gaps in vegetation.
Details
- Multiple returns reach the ground through gaps
- Ground classification for bare-earth models
- Zenmuse L2 records up to 5 returns

Accuracy checks
Prove it with independent check points.
Details
- Hold out check points that are not used in processing
- Report RMS error against your survey control
- Accuracy depends on control, site and workflow
Not a substitute for a licensed surveyor.These tools collect data. A licensed professional surveyor is responsible for boundary, legal and certified surveys.

Deliverables
What you get back
DSM / DTM
Surface and bare-earth models.
More
The DSM includes buildings and canopy. The DTM is ground only, built from ground-classified points.
Contours
Elevation lines for CAD.
More
Generated from the DTM at the interval your plan set calls for.
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.
Orthomosaic
A true-scale, measurable map image.
More
Distortion-corrected, georeferenced imagery for measuring distances and areas. Typically delivered as GeoTIFF.
Profiles & sections
Cross-sections along a line.
More
Cut profiles along a road, rail or pipe centerline from the surface model.
3D mesh
A textured 3D model.
More
Built from nadir and oblique imagery. Good for reviews and stakeholder updates.

Does a drone survey replace a licensed surveyor?
No. It is a data-collection tool. The licensed surveyor sets control, checks accuracy and signs the work.
RTK or PPK?
RTK corrects positions during the flight; PPK corrects them afterward from base station logs. Both still benefit from independent check points.
Do I still need ground control points?
Usually some, plus check points to verify accuracy. Wingtra’s published 3 cm accuracy assumes its recommended PPK workflow.
Lidar or photogrammetry?
Lidar for vegetated ground and thin features. Photogrammetry for open ground and true-color maps. Many jobs use both.
Do you sell GNSS bases and targets?
Yes. Ask about the DJI D-RTK 3 station and Hoodman ground control point kits.
