| Abstract | The Phase Measuring Bathymetric Sonar (PMBS, often called interferometer) is becoming an increasingly popular tool for the shallow water survey community. Recent studies have shown that the bathymetric data quality in maps produced by the best PMBS systems compares with the best current beamforming multibeam echosounders. In shallow waters the PMBS advantages of high accuracy, wide swath bathymetric data, along with co-registered sidescan and texture mapped data products have proved attractive in many applications. The aim of this paper is to illustrate the capabilities of the PMBS sonar in the shallow water applications of nautical charting and environmental mapping, by looking at examples of the data products generated using a widely available commercial PMBS system (the GeoAcoustics GeoSwath Plus sonar). The emphasis is on application of best PMBS survey planning strategies, survey practice and data analysis methods in order to obtain useful survey data. Previous papers have described the theory behind the technology and the best processing methodologies to use when analysing the data. This paper concentrates on the best survey practice aimed at meeting survey objectives, and shows by example how well these objectives can be expected to be met using current PMBS technology. |
