SSI has a fully equipped Hi-Rail (a.k.a. hyrail, highrail or Hy-Rail) vehicle used for scanning and mapping railroad infrastructure using Rail ( RaLi™). The use of RaLi™ to scan railways allows SSI to capture existing track conditions and provide a detailed snapshot of the rail assets including: centenary structures, tracks, switches, frogs, mile marker posts, etc. A 3D CAD file and Digital Terrain Model (DTM) of the track bed can be easily extracted from the LiDAR scan data.
We have completed many projects throughout the nation for various rail clients. A combination of experience, research, testing and innovative techniques has allowed SSI to develop and trademark several techniques for Rail LiDAR applications.
