LiDAR & laser scanning.
Engineering-grade point cloud data.
Airborne and terrestrial LiDAR scanning for infrastructure survey, structural analysis and digital twin creation. Dense, accurate point cloud data delivered in industry-standard formats with full survey control.
Dense point cloud data for complex infrastructure.
Angell Surveys deploys UAV-mounted LiDAR and terrestrial laser scanning (TLS) to capture high-density point cloud data of structures, corridors and built environments. LiDAR provides precise 3D geometry where photogrammetry alone cannot achieve the required resolution or penetration under vegetation.
All scan data is registered to a documented survey control network and delivered as classified, georeferenced LAS/LAZ point clouds in the client's required coordinate system. We produce derivative products including surface models, cross-sections, feature extraction and BIM-ready geometry as required.
LiDAR is particularly effective for structures with complex geometry, areas of limited surface contrast or heavy vegetation cover — making it the preferred capture method for bridges, retaining walls, embankments and dense urban environments.
What we deliver.
From airborne corridor scanning to millimetre-resolution structural capture.
UAV-Mounted LiDAR
Airborne LiDAR capture from fixed-wing or multi-rotor UAV platforms. Suitable for corridor survey, vegetation penetration and large-area capture at engineering accuracy.
Terrestrial Laser Scanning
Static TLS for high-density structural capture. Ideal for bridges, buildings, tunnels and confined structures requiring millimetre-level resolution and complete surface coverage.
Point Cloud Classification
Automated and manual classification of ground, vegetation, structure and noise returns. Delivered as fully attributed LAS/LAZ files to ASPRS standards with complete metadata.
Surface Derivation
DTM, DSM and TIN surface generation from classified point clouds. Used for earthworks design, flood modelling, clearance analysis and corridor profiling.
Feature Extraction
Extraction of structural elements, utilities and asset features from point cloud data. Delivered as 3D DXF, IFC or structured GIS layers for direct use in design environments.
BIM Integration
Point cloud-to-BIM workflows producing Revit and IFC models from scan data. Enables accurate as-built modelling without traditional measured survey methods.
How we work.
Systematic, quality-assured scanning from brief through to classified deliverable.
Project Planning
Instrument selection, scan position planning, survey control design and method statement preparation. TLS network planned to achieve specified accuracy and complete coverage.
Control & Capture
GNSS control established. Scanner positioned and levelled at each station. Data captured with sufficient overlap to eliminate shadow zones and achieve specified density.
Registration & Classification
Scans registered to survey control using target-based or cloud-to-cloud methods. Point cloud classified and filtered to specification with full QA checks.
Delivery
LAS/LAZ, surface models and derivative products delivered with full metadata, scan logs and accuracy reports. Delivered in client-specified coordinate system and format.
