Fugro has announced the development of a new lidar mapping system for bathymetric applications, which is says speeds up data acquisition and improves data quality.
Fugro has said that Rapid Airborne Multibeam Mapping System (Ramms) uses field-proven technology to deliver an efficient and cost-effective solution, dramatically improving upon other bathymetric lidar mapping capabilities.
Traditional bathymetric lidar technology requires customers to compromise between price, depth penetration and data density,” said Fugro USA president and regional director for Fugro’s Marine Division in the Americas Ed Saade. “With Ramms, there’s no trade-off. It can achieve 3-Secchi disk depth penetration at a higher observation density than any comparable system on the market - and we’ve recorded seafloor depths as deep as 42m during a recent survey.”
Described as a first-of-its-kind multibeam lidar system, RAMMS was developed in partnership with Areté Associates. The system utilises push-broom laser technology and is based on 20 years of cutting-edge military technology for mine detection, developed via the US Navy Small Business Innovated Research programme. It is also underpinned by over 25 years of bathymetric lidar experience for nautical charting.
The sensor’s compact design allows for rapid deployment on small aircraft of opportunity, including unmanned, fixed-wing aircraft. The resulting operational efficiencies are enhanced through rapid processing and data transfer capabilities.
“We believe Ramms will bring significant value to hydrographic organisations, coastal zone/floodplain managers and engineers,” said Saade.
Saade added that the system has already been used on a successful hydrographic charting demonstration project recently performed in Belize, covering 165km2. Fugro is currently using Ramms to complete several large-scale surveys in the Americas with projects in other regions expected to follow.
