The Port of Melbourne is responsible for many wharves and waterside assets. Periodic inspections of these assets are required to monitor their structural integrity. These inspections are usually conducted onsite with photography evidence and usually have some element of risk to the inspector.

The Port of Melbourne’s Spatial Information service department is investigating innovative survey techniques to mitigate some of the risk and provide quantifiable results. Marine vessel mounted LIDAR provides accurate data results of the wharf structure but tells little of the surface condition. So, some photogrammetric techniques are being trialled to provide structure and surface condition assessments.
