Quantum Spatial, Inc., an NV5 company, announced their new sensor platform that is designed to improve the efficiency of data collection, while delivering high-density, high-resolution and highly accurate results.  The Comprehensive Low-Altitude Sensor Solution (CLASS) combines dual-look LiDAR, RGB and NIR nadir imagery and forward-looking oblique imagery into one platform that can be affixed to a rotary wing platform.

The CLASS platform can support multiple use cases in a variety of sectors that involve corridor and specialty wide-area projects, including rail and roadway transportation corridors; electric transmission and distribution; inspection of infrastructure such as bridges, buildings, and dams; airports and pipelines.  It is also suited for examinations of riverine environments and assessing geophysical risk from landslides and volcanoes.

CLASS combines the following technologies into a single platform:

  • Dual Riegl VUX LR LiDAR sensors
  • Applanix POS AV 610 IMU (airborne global navigation satellite system (GNSS) and Inertial Navigation System (INS))
  • Phase One RGB camera
  • Phase One NIR camera
  • Phase One oblique RGB camera
  • Marshal electronics high-definition video

With these technologies, Quantum Spatial can provide high-density LiDAR point clouds at 50 to 100 points per square meter, high-resolution nadir imagery for mapping with common resolutions ranging from 1/3 inch to ½ inch and resolution in oblique that enables analysts to read signs, inspect infrastructure or accurately catalog asset conditions.  The CLASS platform works at altitudes of 300 to 1,640 feet above ground line (AGL).
