Mobile lidar

Terrestrial Mobile lidar (TML) uses a laser scanner(s) in combination with Global Navigation Satellite System (GNSS) receivers, Inertial Measurement Unit (IMU), and Distance Measuring Instrument (DMI) to produce accurate and precise geospatial data from a moving terrestrial platform.

lidar sensors use an active (projected) light signal to measure the relative x, y, z, position and reflective properties of a point on an object. In practice this results in a point cloud with image qualities similar to other remote sensing technologies.

Key factors to consider when determining if TML is appropriate for a  survey project:

  • Safety
  • Project deliverables desired
  • Budget
  • Project time constraints
  • GNSS data collection environment
  • Terrain and length/size of project
  • Traffic volumes and available observation times
Acquisition Platforms
  • Vehicle Mount
  • Rail Mount
  • Off-Road Vehicles
Example Applications
  • Mapping of Roadway Corridors and¬†Infrastructure
  • Railway Corridors
  • Pipeline Corridors
  • Road Surface Measurements
  • Construction Site Development and Monitoring
  • GIS Mapping and Asset Management
  • Utility Inventory
