01
Corridor & wayleave engineering
Route geometry, clearance and access design along energy and transport corridors.
Airborne LiDAR & Topography
The ground beneath the canopy, measured to survey standard. Dense airborne LiDAR returns are classified to recover bare earth, structure, vegetation and asset clearance in a single pass.
LiDAR pulses penetrate vegetation to return a dense point cloud, and automated classification separates ground, vegetation and man-made assets. The recovered bare-earth surface is the elevation model that corridor and site engineering actually needs — surveyed efficiently over terrain a walking crew could not cover in the timescale.
The same cloud is interrogated for asset clearance: distances to conductors, tree canopies and structures along energy corridors, plus cross-section geometry for route and wayleave design. Vegetation height and density layers support ongoing management programmes.
Volumes, slopes and drainage profiles are computed directly from the classified cloud. Deliverables are issued in the projection and file formats your designers use, with a full method and accuracy statement for audit.
