Mobile LiDAR: Transforming Data Collection

Mobile LiDAR (Light Detection and Ranging) is a powerful mapping method that uses laser scanning to identify roadway assets and related infrastructure quickly, accurately and cost efficiently.  Typically, LiDAR captures data for 30-50 miles of right-of-way a day, making it the ideal solution for use in asset management, geospatial (GIS), and surveying and mapping.

Why go LiDAR?

PILLAR offers the Leica Pegasus Two Ultimate, a laser scanning mapping technology that identifies — down to the millimeter — a wide variety of assets along the roadway.

You can utilize the unit’s two back-to-back cameras and create a 24 MP 360-degree image to the LiDAR profiler data in various lighting conditions and vehicle speeds. The camera helps with asset visualization by providing photographs of your assets to go along with the LiDAR scan. Another add-on option is a pavement analyzer, which measures the amount of cracking and roughness of the roadway.

Fully Automatic Feature Extraction

PILLAR’s mobile LiDAR service uses fully automatic feature extraction, rather than other companies’ semi-automatic extraction. Whereas the process formerly took months, our system can get it done in days or weeks*.

More than 20 assets can be pulled from the GIS system, including:

  • Signs
  • Guardrails
  • Bridge clearances
  • Trees
  • Mowing Acreage
  • Striping
  • Ditches
  • Overhead utilities

If you don’t see an asset above, contact us to learn more about our full capabilities. In addition, we can export data visualizations using a colorized point cloud, JPG, video files, and more.

*Timelines will vary from project to project and at times will exceed one or two days.

The accuracy you need

PILLAR provides a few different methods of scanning your asset based on your needs.

Relative Accuracy
Typically used for mapping grade work and obtaining inventory and measurements, relative accuracy is the exact relationship between point to point within the point cloud obtained.

Absolute Accuracy
Typically used for design or survey grade work, absolute accuracy is the exact relationship between the point collected and its true position – latitude, longitude and elevation – on the ground. This requires setting control points by our survey crews along the scan path so that specific identified points in the point cloud can pull the point cloud to the control point (known location). The more control points set, the higher the accuracy.

When should I use which accuracy? Is one better than the other?
That depends on several factors – desired outcomes, timeframe, and budget.
