Options for Offshore Backscatter Polygons & Data item by id

This layer shows the location and basic information for bathymetric surveys containing backscatter data. A zip file of the backscatter image files (e.g. geotiffs) for the survey can be downloaded using the URL link provided. Note that there can be more than one polygon per survey and these will link to the same zip file for the entire survey. For access to the data underlying the images please contact Marine Enquiries (offshoredata@bgs.ac.uk). The majority of the data were collected and processed for the Maritime and Coastguard Agency (MCA) under the Civil Hydrography Programme. If further processing is required, BGS can provide a quote.
