Mobile & Laser Scanning — vehicle LiDAR and handheld SLAM

Mobile & Laser Scanning

Corridor-grade LiDAR and SLAM scanning for roads, utilities, plants and buildings—fast capture with survey alignment and engineering-ready outputs.

Mobile LiDAR Handheld SLAM Control & QA

High-speed capture, survey-grade alignment

We deploy vehicle-mounted LiDAR for corridors and handheld/backpack SLAM for indoor and GNSS-challenged spaces. Data is tied to a control network, then adjusted and cleaned to deliver accurate plans, sections and rich 3D assets.

Typical use cases: highways and RoW mapping, utilities & streetscapes, plants & brownfield documentation, station buildings and campuses, stockpiles and yards.

Dense 3D capture

Millions of points/sec with calibrated intensity; optional 360° imagery.

Survey alignment

Control points, GNSS/IMU solutions, loop closures & checkpoints.

Feature extraction

Centerlines, kerbs, poles, signage, floor edges, MEP & structural.

QA & reporting

Strip adjustment logs, residuals, RMSE summary, control diagrams.

Where it shines

Fast, complete coverage—great for linear assets and complex spaces.

Roads & Streetscapes

Centerlines, kerbs, signage, clearances, cross-falls & sections.

Utilities & RoW

Poles, lines, manholes, drainage, verge inventory & encroachments.

Plants & Facilities

SLAM indoors for pipes, racks, floors & structural mapping.

Buildings & BIM

Floor plans, elevations, deviation checks, mesh & BIM handoff.

Mining & Yards

Stockpile volumes, conformance, haul roads and safety audits.

Rail & Metro

Track & platform scans, clearances, OHE & station environs.

Process

How We Work

Control-first approach with documented accuracy and handover.

Step 01

Scope & Control

Define CRS, control/checkpoints, density, imagery, safety & traffic plan.

Step 02

Capture

Mobile LiDAR runs, SLAM loops indoors, 360° pano & ground photos.

Step 03

Processing

Strip adjustment, loop closure, classification, noise cleanup & colorize.

Step 04

Extraction

Centerlines, kerbs, edges, floor lines, features & sections.

Step 05

QA & Review

Checkpoints & residuals, RMSE report, peer review & revisions.

Step 06

Deliver

LAS/LAZ, E57/RCP, DWG/DXF, OBJ/FBX + handover notes & CRS doc.

FAQ

Quick Answers

Mobile LiDAR + SLAM scanning basics for project teams.

How accurate is the point cloud?

Relative 1–3 cm typical; absolute 2–5 cm with good control & visibility. We include RMSE and residual tables.

Can you deliver drawings, not just points?

Yes—plan/profile, sections, kerb/edge layers and selected features in DWG/DXF, plus meshes and orthos if needed.

What about traffic and permissions?

We coordinate with site teams for traffic management, timings and safety. Permissions are planned during scoping.

How big an area can you cover per day?

Urban corridors: typically tens of km/day; plants/campuses vary with density. Share scope and we’ll propose a plan.
