Mobile laser scanning adds another dimension to surveying. As the name suggests it is the application of laser scanning from a moving system, usually a vehicle. A mobile survey system is comprised of a navigation system and a laser scanner, and usually includes a camera.

The navigation system is a combination of a survey-grade GPS, an Inertial Measurement Unit (IMU), and wheel encoders that track the distance travelled. We process the information from the navigation sensors to produce a time-stamped trajectory.

The laser scanner measures up to 1 million points per second while the vehicle travels along the survey route. The massive coverage of point data enables thorough capture of a wide variety of survey features.

The 360° panoramic camera provides capture of street-view imagery. The imagery can be overlaid on the point cloud to enable an immersive 3D interaction suited to general feature mapping. The 360° imagery is often presented as a 360° video or in GIS database form.
