Mobile LiDAR Mapping FAQs
Mobile LiDAR mapping has become more affordable in recent years. While there are many questions about how it works, it’s benefit , data format, how its is collected, we tried to cover the most frequently asked questions below.

Q: What is Mobile LiDAR and what is it used for?
A: Mobile LiDAR is a method of collecting LiDAR data from a moving vehicle
LiDAR stands for Light Detection and Ranging. It is an active remote sensing method that uses a laser to measure ranges (variable distances) to the surrounding environment. When the laser is combined with GPS and Inertial Navigation System (INS) data, a precise dimension, shape and location on Earth is generated in 3D.
Mobile LiDAR is used to map and survey corridors from the street level with high accuracy. Roads, highways and railways can be mapped at high speed without disturbing traffic.
Q: What are the benefits of Mobile LiDAR?
A: The benefits of mobile LiDAR include:
- High density, high accuracy geospatial data
- the Ideal solution for extracting street features as lines, polygons, or points.
- Cost effective on linear projects
- Provide rapid documentation of existing conditions.
Q: What is the difference between Aerial LiDAR and Mobile LiDAR
A: Aerial LiDAR Versus Street Level LiDAR
Street Level LiDAR
Q: What type of data is produced by Vehicle Based LiDAR?
Vehicle Based LiDAR produces Pointcloud Data
In Surveying and Mapping, Mobile LiDAR data is always geo-referenced to either a local or a global coordinate system. The most common pointcloud data format from mobile lidar include: LAS, LAZ, XYZ
