Raster Charts XL are derived from raster-based material 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. Raster Charts XL coverage is available depending on permissions granted by contributing nations worldwide.
Raster Charts XL provide an immediate image which is symbolised and ready to use and are available as individual charts for different geographic areas at discrete scale levels. No additional software is required as they can be opened in any image viewer. Non-marine areas are provided as transparent pixels to allow the inclusion and display of digital land mapping, such as from a National Mapping Agency, OpenStreetMap or Google Maps. The familiarity of the nautical chart for the marine area is retained.
Raster Charts XL are available in GIS compatible file formats (GeoTIFF) as individual charts and panels, or as a seamless data service from OceanWise and our Licensed Partners. Take a look at our demonstration site or download our sample data, including our Marine & Coastal Data Products User Guide, to try it for yourself.
