What is mobile mapping?

Mobile mapping mounts LiDAR, cameras, and navigation sensors on a vehicle or backpack to capture corridor-scale 3D data while moving—faster than static scans for roads, rails, and large sites when accuracy requirements allow.

What is SLAM in surveying?

SLAM (Simultaneous Localization and Mapping) estimates sensor motion and builds a map at the same time—used indoors, underground, or anywhere GNSS is unavailable, often with handheld or backpack LiDAR.

How accurate is mobile mapping?

High-end MLS often targets roughly 1–5 cm relative accuracy in good GNSS conditions; urban canyons and long gaps without control degrade drift. Always align to control and use project-specific QA.

Mobile Mapping & SLAM — Vehicle, Backpack & GPS-Denied Survey

Vehicle-mounted (MLS)

Roads and rails at driving speed. GNSS/IMU couples with laser scanners; control from checkpoints limits drift. Compare with mobile mapping trucks product context and LiDAR fundamentals.

Backpack & handheld

Pedestrian speed for campuses, trails, and facilities—often SLAM-forward with GNSS when available. Great for areas a truck cannot reach.

When to choose static TLS

When you need maximum precision on discrete facades or tight volumes, tripod terrestrial LiDAR may beat mobile capture—budget time for registration.
