It is a continuous LiDAR scanning method using a moving platform, either vehicle or drone, to capture point cloud data along an entire linear infrastructure route.

Drone LiDAR can access terrain vehicle-mounted systems cannot reach, such as steep embankments or areas without road access, making it preferred for many rural alignments.

Corridor surveys that would take weeks using traditional ground methods can often be completed in days using continuous LiDAR scanning passes.

Yes, faster flight speeds reduce point density per unit length, so speed must be balanced against the density required for the project.

Typical deliverables include a corridor terrain model, regular cross sections, and extracted features like drainage, embankments, and existing infrastructure.

Yes, the dense terrain model captured along the corridor allows engineers to identify drainage patterns and embankment condition issues from the data.

With proper GPS and inertial correction, corridor LiDAR surveys typically achieve centimeter-level accuracy suitable for engineering design work.

The underlying LiDAR scanning method is similar, though railway projects often require additional precision around track geometry and clearance envelopes.

It is the process of slicing the continuous point cloud at regular intervals along the corridor to generate profile views used in engineering design.

Yes, ground control points placed along the route help verify and anchor the continuous scan to survey-grade coordinate accuracy.
