Putting Research into Practice: 3-D Mapping of Bridges and Riverbeds with Underwater Sonar
The Minnesota Department of Transportation (MnDOT) has released a report that describes methods and practices for using sonar in 3-D mapping of riverbeds and below-surface bridge substructures. MnDOT bridge inspectors have used underwater inspection technologies to examine erosion, and in certain areas, sonar technology – which gathers underwater acoustic data into point clouds for imaging 2- and 3-D models – offers safe examination options.
