Marine Themes Vector

OceanWise Global > Overview > Marine Themes Vector
Comprehensive, flexible and intelligent marine mapping for manipulation and analysis

Marine Themes Vector is our intelligent dataset, engineered into logical data layers for easy loading and efficient use in desktop and web-based Geographic Information Systems (GIS).

Data attributes have been designed with analysis and querying in mind. Chart boundaries have been removed to create a seamless, simplified dataset across charts. This dataset is available in GIS compatible file formats or as a data service from our Licensed Partners. The data is derived from authoritative material obtained from the UK, and other, Hydrographic Offices, as well as comprehensive source data where available.

Marine geographical features are grouped according to type as follows:

  • Elevation
  • Shipwrecks and Obstructions
  • Industrial Facilities
  • Transport
  • Administrative and Management Units
  • Geographical Regions

These data layers provide a comprehensive marine map and are ideal for applications where the user needs to choose, analyse or derive the features, based on data type or attribute, to be displayed.

Suitable symbology is provided as standard (e.g. Esri Layer, Cadcorp NOL files) so the data is ready for immediate use in GIS.

To learn more about data content, check out our comprehensive Feature Catalogue or Request our Sample Data, that includes our Marine & Coastal Data Products User Guide.
