Transmap Corporation has been in the infrastructure management business for the past 17 years. They have seen a lot of digital mapping technology come and go. In this blog post they provide a great overview of how they used Mobile LiDAR to inventory street lights in El Paso, Texas.
Transmap’s mobile mapping system uses a Sick Laser Scanner. It is installed on top of a van in a vertical position pointing to the right side of the vehicle. The laser captures 3D points with an oscillating mirror and a vertical field of view of 100 degrees at a frequency of 75 Hz. Each vertical scan consists of 200 points.
This may not be the highest resolution scanner on the market, but it seems to get the job done.
