TECHNICAL OVERVIEW
LiDAR‑Based Spatial Data Acquisition & High‑Resolution Imaging
Survex provides integrated LiDAR laser scanning and high‑resolution photographic documentation for engineering, construction, and infrastructure projects. Our workflow is designed to deliver high‑accuracy, geo‑referenced datasets suitable for analysis, reporting, and long‑term asset management.
1. LiDAR Data Acquisition
Survex employs advanced LiDAR sensors capable of generating dense point clouds with millimeter‑level precision. Deliverables include:
Geo‑referenced point clouds (LAS/LAZ formats)
3D mesh models (OBJ/PLY)
Digital surface models (DSM)
Cross‑sections and profiles
Volume, area, and dimensional calculations
Applications:
As‑built documentation
Progress verification
Deformation monitoring
Earthwork volume calculations
Clash detection and design validation
2. High‑Resolution Imaging
High‑resolution photography is captured concurrently with LiDAR scanning to enhance visual interpretation and provide photorealistic context.
Deliverables:
High‑resolution image sets
Orthophotos
Annotated visual reports
Photo‑textured 3D models
