Aerial & Mobile LiDAR Scanning


Aerial LiDAR (Light Detection and Ranging) and Mobile LiDAR are at the forefront of surface laser technology as the preferred surveying method for large-scale  infrastructure projects.


Our LiDAR capabilities augment Meridian's expert land surveying and scanning services to provide clients with the most advanced accuracy and data capture quality for land surveying, mapping and laser scanning applications.


Our field operations, supported by our highly experienced Survey and Laser Scanning departments and data acquisition specialists, utilize a collection of post-processing software to assure the data collection meets all applicable spatial data standards.



Aerial LiDAR

Led by our licensed UAS Pilots and field survey crews, our state-of-the-art UAS (Unmanned Aerial System) aerial drone combines lightweight, on-board survey grade GPS, a FOG inertial measurement unit, and a 32-laser Velodyne LiDAR scanner to capture highly accurate data at unparalleled collection rates. This simultaneously provides:


    • Large, detailed datasets collected at 700,000 points per second capturing   millions of 3D data points
    • Optional high resolution aerial photography and infrared thermal imaging
    • Efficient workflows to aggressively meet time-intensive project schedules
    • Non-invasive practices that enhance site safety


Mobile LIDAR

Mobile LiDAR mapping is a high speed, accurate surveying technique utilizing state-of-the-art laser sensors, coupled with advanced GPS-based positioning and immersive cameras that collectively produce corridor wide, full-color, LiDAR point cloud data. The LiDAR data is post-processed and delivered with a variety of derivative products, such as, terrain models, topographic mapping, asset databases, 3D models, and clearance studies.


Benefits

This survey approach benefits clients with overall cost savings due to schedule compression and the re-use of the data by multiple engineering disciplines for future projects.
