Case Examples 29 LiDAR remote sensing in this case study is better informing decisions through increased data coverage and confidence, and at a lower cost than traditional methods. As a result of this work, VTrans reported planning to scale up the program and implement ground-based LiDAR surveys at other locations such as future repair projects and existing rock slopes and retaining walls.
