What kind of data is available for Marine Mapping?
Raster Charts
Raster Charts provide electronic versions of familiar nautical paper charts and are derived under licence from the UK, and other, Hydrographic Offices. They can be opened using any image viewer software and are geo-referenced for use in geographical information systems (GIS).
Raster Charts are ideal for applications where a set of familiar features and related symbology is required for reference or as a backdrop to other data.
Raster Charts are available at Large Scale for estuaries and harbours (greater than 1:30 000), Medium Scale for coastal waters (1:30 000 to 1:150 000) and Small Scale for sea areas (Less than 1:150 000).
Raster Charts XL (Excluding Land)
Raster Charts XL (Excluding Land) are Raster Charts with the usual mustard-shaded land areas removed so that customers can pair charts with land mapping of their choice.
Marine Theme Vector
Marine Theme Vector products are provided as individual themed layers and contains feature attributes designed with analysis and querying in mind. Chart boundaries have been removed to create a seamless, simplified dataset with unique identifiers for data linking. There are eight layers describing geographical regions, administrative areas, transport routes, industrial facilities, obstructions and shipwrecks, elevation, sea-bed geology and tides and tidal currents.
Marine Themes Digital Elevation Model (DEM)
Marine Themes Digital Elevation Model (DEM) is a separate, seabed surface model, comprising detailed and accurate data of the seabed. The dataset utilises the most recent, commercially available single and multi-beam survey and LiDAR data, assessed and carefully selected in a deconfliction process. A coverage layer is also available to ensure the source of the data is always clearly defined.
International Marine Mapping
International Marine Mapping is also available for selected regions worldwide depending on international agreements. Please contact us to confirm availability for your area-of-interest.
Marine Themes
Ideal for general situation awareness, planning, site selection and investigation and outline engineering design.
Product DetailsMarine Themes are supplied as half-degree tiles for your area of interest.

The dataset utilises the most recent, commercially available single and multi-beam survey and LiDAR data, assessed and carefully selected in a deconfliction process. A coverage layer is also available to ensure the source of the data is always clearly defined. The product is supplied as half-degree tiles where available (1 arc second) along with two-degree tiles (6 arc seconds) included in the price. Not to be used for navigation.
