Figure 1: A road section near Helsinki, where the structure of the road has clearly failed. The arrows show the direction of the crossfall in each lane and for visualization purposes all the values sloping from left to right are painted red illustrating the wrong sloping direction in a curve.
GIS Resources recently published an article featuring Nordic Geo Center and how RIEGL Mobile Mapping LiDAR technology is being utilized to produce road surface condition parameters that pass the official VTI (The Swedish National Road and Transport Research Institute) tests conducted in Sweden. Not all commercial mobile LiDAR systems can produce accurate enough data to meet these requirements and that was a key component in Nordik Geo Center’s selection of RIEGL Mobile LiDAR for this project, due to its high precision and exceptional image quality.
Figure 2: RIEGL VMX measurement principle: The image illustrates the “crossfire” scan lines of the two scanners (colored in red and green). The foreground shows the VMX point cloud colored with the reflectance attribute, the background shows the optional RGB colored point cloud.
Learn more about how Nordic Geo Center has spanned the last decade going from a RIEGL VMX-450 to a VMX-2HA, and how LiDAR has opened new possibilities in road surveying that meet and exceed today’s requirements in the field.
