4th Mainland Bridge Route Drone Survey Project – Lagos, Nigeria
As part of pre-construction planning for one of Nigeria’s most ambitious infrastructure projects, OSGOF Consultancy Limited deployed advanced drone technology to capture high-resolution aerial data along the proposed 4th Mainland Bridge route in Lagos State.

The survey enabled planners to:
- – Map the entire route corridor with centimeter-level precision
- – Generate orthophotos, digital terrain models (DTMs), and 3D surface models
- – Identify land use patterns, obstacles, and topographic features along the alignment
- – Support environmental impact assessments and design decisions
This project demonstrates our ability to deliver fast, safe, and scalable drone mapping solutions for large-scale infrastructure development.
