| Résumé | (disponible en anglais seulement)
The British Geological Survey (BGS) is recognised as a national and international leader in characterising the geological nature of the seabed and shallow
sub-seabed, from developing novel methodologies, to research and applied science. The BGS, often working together with academics and industry-based scientists, are perpetually active in innovating new data processing and interpretation techniques,
including remote-sensing and statistical protocols, automatic feature-detection algorithms, and database solutions.
There is no one-size-fits-all approach for seabed mapping, and standardisation of the flow from multibeam echosounder (MBES) data
to interpretation and map production, remains an elusive goal. Numerous factors must be considered in determining the most appropriate approach for substrate mapping. These include the planned end user, mapping objective, scale, data quality, and
geological context. A crucial step in the mapping process is to take account of these variables, and determine the most suitable mapping methodology.
Considering these conditions, this study elucidates the decision-making process behind the
selection of a mapping technique and illustrates the application of a variety of approaches to produce maps for a range of end users. The relative merits and caveats to these outputs are considered, with a particular focus on the requirements of
different end users. |
