Mobile Mapping

Mobile Mapping is the newest technology used to collect mass quantities of terrestrial LiDAR at both mapping grade and survey grade accuracies. The concept of mounting two 3D lasers, 4 to 6 cameras, a military grade IMU, and two GPS receivers to a vehicle and collecting continuous point data clouds at highway speeds provides the most efficient and accurate method of data collection along highways, secondary roads, beaches and other routes permitting vehicle access.

LiDAR Mobile Mapping Technology allows for the automated data/asset extraction of:

  • Light poles
  • Power Poles
  • Guard Rails
  • Signs
  • Roadway Break Lines
  • Lane Dividers
  • Fire Hydrants
  • Storm and Sanitary Sewer Manholes |
    Drop Inlets | Catch Basins
  • Water Valves
  • Sidewalks and Drives
  • Towers
  • Pavement DTMs
  • Building details
  • Tree locations
  • Landscaping
  • Fencing
