How LiDAR mapping accelerates highway corridor design

Highway corridor studies depend on accurate terrain models, crossing points, and right-of-way data collected early in the project cycle. When schedules are tight, traditional ground surveys alone may not capture enough detail across long or inaccessible alignments.

Aerial LiDAR combined with GNSS control allows Bhygraph to deliver dense, georeferenced point clouds that support alignment design, earthwork quantities, and multidisciplinary reviews. Classified surfaces help teams distinguish ground, vegetation, and structures before field teams mobilise for targeted verification.

For transport programmes in Cameroon and across the region, integrating LiDAR with topographic surveys and engineering studies creates a practical workflow from feasibility through detailed design.

Bhygraph supports clients with acquisition planning, data processing, and deliverables such as DTMs, DSMs, and orthophotos formatted for CAD and GIS environments. Clear documentation helps contractors and designers use the data consistently throughout the project lifecycle.
