Mobile LiDAR

Mobile LiDAR has many advantages over traditional survey methods for corridor mapping. Mobile LiDAR systems operate at up to 1,000,000 measurements per second at 5mm accuracy. Coupled with the ability of being mounted on a vehicle and driving at highway speeds, means Mobile LiDAR can extremely quickly capture many kilometres of a corridor at a higher point density when compared to traditional survey methods. The higher point density provided by Mobile LiDAR also provides a better perspective and accurate representation of the subject area when compared to traditional survey. Utilising Mobile LiDAR also reduces the risks involved in having survey personnel in high risk situation as the data can be captured remotely, day or night and under normal traffic conditions, minimising the time survey personnel are required on the pavement working amongst traffic. This too comes with cost savings as Mobile LiDAR greatly reduces the requirement for traffic control systems when compared to traditional survey methods. This in turn minimises the disruption to traffic flow. Obtaining traffic management approvals can involve local councils and police and is generally a 4 week turn around. When working to a tight programme these additional constraints can be reduced by utilising MLS. In many parts of the world, MLS is now the preferred option for data capture unless circumstances mean it cannot be utilised.
