Underwater Asset Imaging
The surveying and imaging of underwater assets is an essential tool for asset management, asset monitoring/repair and the resource consenting process. The surveys typically consist of Multibeam Echo Sounder Surveys (MBES), Side Scan Sonar Surveys below the water combined with Mobile Laser Scanning (MLS) of structures above the water to create 3D point clouds. The vessels used are purposes built survey vessels ranging in size from 5-7m in length fitted with state of the art positioning, motion sensors and portable survey computers.

Challenge 1: Managing and understanding the six degrees of vessel motion using a survey quality Inertial Navigation System (INS) to correct TLS and MBES data increases the quality and accuracy of your final data sets.
Challenge 2: The careful online acquisition, management and processing of large volumes of point cloud data in real time is key to reducing post processing effort and deriving accurate results. Daily data volumes range from the hundreds of Gigabytes to Terabytes of data.
