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.
