Vehicle-mounted and SLAM mobile mapping in an urban corridor

Mobile Mapping

Vehicle-mounted LiDAR and SLAM for rapid, safe 3D capture of roads, rails, utilities, streetscapes and interiors - ready for CAD/GIS.

Overview

Convex Geomatics Ltd. delivers fast, safe mobile mapping by combining vehicle-mounted LiDAR, 360° panoramic imaging, backpack mounted LiDAR and handheld SLAM LiDAR. We capture dense, georeferenced 3D at highway speeds and continue seamlessly into GPS-denied interiors such as tunnels, plants, and parkades-producing datasets that drop cleanly into engineering design, asset inventories, and digital twin programs.

Speed & safety first. Working from the roadway means fewer lane closures and less field exposure. Our vehicles cover long corridors efficiently while SLAM crews handle tight or obstructed spaces, so your network is mapped with minimal disruption.

Defensible accuracy. GNSS/IMU trajectories, survey control integration, and SLAM optimization deliver centimetre-level results you can trust. Continuous checks and transparent QA/QC make the data approval-ready for owners and consultants alike.

Rich, review-ready content. We provide full-coverage point clouds and colorized 3D with synchronized 360° imagery for rapid feature confirmation. Curb lines, lane markings, signage, utilities, bridges, and clearances are captured in one pass, giving teams a shared visual record for decisions and design.

Fusion when it matters. Need rooftops, bridge decks, or cliff faces? We can merge UAV and terrestrial scans with mobile LiDAR to fill occlusions and complete the vertical picture-aligned to your project control, datum, and CAD/GIS standards.

Tell us what you need measured and to what tolerance. We'll recommend the most efficient mix of vehicle, backpack, SLAM, and UAV to meet your schedule and budget, and deliver clean, documented data that's ready for design and asset management.

FAQ

Mobile LiDAR uses GNSS/IMU georeferencing and excels outdoors; SLAM estimates motion from sensor observations and works in GPS-denied interiors.
With proper calibration and control, typical deliverables are ±1–5 cm and suitable for engineering workflows.
Yes, mobile, and UAV LiDAR scans are fused into a single coordinate framework with consistent datums and projections.
