WSI has successfully mapped a variety of transportation corridors including highways, streets, railways, bridges, hiking and cycling trails using LiDAR and orthoimagery. Airborne LiDAR can efficiently provide critical infrastructure information without concern for safety hazards posed to ground-based survey crews while working in traffic zones. Data collected is used not just to define the transportation asset but entire corridor networks. WSI develops 3-dimensional surfaces for grade analysis, building vectors, vegetation height and density and utility infrastructure. The comprehensive geometric dataset allows transportation engineers the ability to address broad strategic issues such as traffic planning, lane widening, noise models, vegetation management, safety, right of way boundaries, hazard mapping and emergency response.
