This map layer is a Web Map Service provided by a third party. Data is automatically updated and made available by the data owners, but can be viewed in the NMPi portal. For detailed information about layers supplied by third parties, we recommend contacting the data owner directly
OceanWise's Raster Charts XL are derived from raster-based hydrographic charts obtained under licence from the UK, and other, Hydrographic Offices where land and other non-marine features have been removed. This provides familiarity for users who work with nautical charts and has the advantage of being able to combine it with any land mapping, or aerial imagery, of your choice.
