Professional aerial LiDAR survey for infrastructure, topographic and structural applications. Dense point cloud capture with centimetre-accurate RTK georeferencing. LAS output compatible with all major processing platforms.
Where photogrammetry captures surface texture, LiDAR captures geometry. In vegetated areas, complex structures and low-light conditions where photogrammetry struggles, LiDAR delivers the precise 3D data your project requires.
Every engagement follows a structured methodology that ensures accurate data, legally defensible outputs and actionable results.
Flight altitude, speed and overlap designed to achieve the required point density for your application. RTK GNSS ground control established for accurate georeferencing.
Systematic LiDAR capture across the survey area. Multi-return capability captures vegetation canopy and ground returns simultaneously.
Raw LiDAR returns processed, classified and georeferenced. Ground, vegetation, structure and noise classifications applied. Accuracy report generated.
Classified LAS point cloud delivered. DTM and DSM generated from ground and surface returns. Integration support for your GIS and analysis platform.
CAA GVC authorised. ITC Level 2 certified. ISO 18434-1 compliant. Every Canopy engagement is backed by the qualifications, methodology and insurance your procurement team requires.
LiDAR multi-return capability captures returns from both the vegetation canopy and the ground surface beneath. This enables accurate terrain modelling in areas where photogrammetry cannot see through to the ground — woodland, scrub, hedgerows and dense vegetation corridors.
LiDAR captures the precise 3D geometry of complex structures — pipe racks, lattice frameworks, cable corridors and civil infrastructure — with a density and accuracy that photogrammetry cannot match on non-textured surfaces.
Modern LiDAR payloads deliver hundreds of points per square metre at survey altitude, enabling detailed surface modelling for structural analysis, volume calculation, change detection and engineering design.
Multi-return LiDAR captures first and last returns from every laser pulse. First returns represent the canopy or structure surface. Last returns represent the ground. Both are delivered as separate classified layers in the LAS output.
Digital Terrain Model (ground surface, vegetation removed) and Digital Surface Model (including all above-ground features) generated from the same LiDAR dataset. Both delivered as georeferenced GeoTIFF alongside the full point cloud.
The highest-value survey combines LiDAR geometry capture with photogrammetric texture capture. LiDAR delivers precise 3D structure; photogrammetry delivers the visual context. Canopy delivers both datasets from a single mobilisation, aligned to the same coordinate system.
