The NCWG, and the publications for which it is responsible, provides a core of expertise on the basic concepts of charting. Whatever physical form the chart or publications may take, the fundamental concepts and elements of marine cartography remain the same.

NCWG has been tasked by HSSC to:

  • Revise, develop and maintain IHO Publication S-4"Chart Specifications and Regulations for INT Charts";
  • Revise, develop and maintain Part A of IHO Publication S-11 Guidance for the Preparation and Maintenance of International Chart Schemes";
  • Maintain INT1, INT2 and INT3 (with national Hydrographic Offices' assistance);
  • Develop new symbology.
