About
An aerial survey team that hands over data you can build on
Left Off plans, flies and processes aerial surveys for construction, infrastructure and land development in Saudi Arabia. One team owns the flight plan, the ground control, the processing and the delivery, so the data that reaches you has been checked from start to finish.
How we work
- 01
Scope
Area, accuracy and deliverables are agreed in writing before anyone flies.
- 02
Fly
A fixed flight plan with RTK or PPK positioning and observed ground control.
- 03
Process
Photogrammetry in Pix4Dmatic and 3Dsurvey, checked against the control points.
- 04
Deliver
Files ready for CAD and GIS with an accuracy report, and raw data within 24 hours of each flight.
Services
Topographic survey
Elevation models, bare-earth models and contours tied to ground control.
Progress monitoring
Repeat orthomosaics on a fixed flight plan, so every visit compares directly.
Volumes
Cut, fill and stockpiles from the difference between two models or two visits.
3D models
Point clouds and reality models of sites, structures and terrain.
Raw data for your team
Photos, PPK logs and control coordinates with an accuracy report.
Visual documentation
Aerial video up to 6K and 360° panoramas from fixed points.
