The image above showcases an example of mobile LiDAR data, displaying virtually all nearby surface features in great detail. SkyTech gathered this data during a recent mobile LiDAR project in Las Vegas. On the right side of this image the Mirage Hotel is visible, and several other types of structures and features are well resolved, such as palm trees, poles, posts, signs, and pedestrian areas. This collection is from one pass of the vehicle at 60 km per hour, however this data is rich and accurate enough to detect virtually any feature along the road. With technological developments offering increased density, accuracy, and reduced collection costs, this type of data is available to more projects than ever before.
Mobile LiDAR (or mobile laser scanning) is a surveying method involving one or more laser scanners being mounted to a moving vehicle to gather spatial data. There is a wide range of applications for this technology including inspection of road infrastructure and road surface conditions, as well as complete asset management for urban and industrial areas.
With the use of post processing software, and high density data, the extraction and categorization of complex features from basic point clouds is performed, rapidly identifying light poles, intersection features, trees, culvert bases, and road markings. Essentially all features visible to the laser can be identified. This is particularly useful for engineers looking to obtain accurate positional data at a fraction of the cost and turnaround time compared to conventional methods.
