SNPWG has to develop a Product Specification to enable ECDIS manufacturers to build software able to display NPUB information on an ECDIS screen.
The SNPWG Wiki administration is trying to provide the files in a convenient way; but we can not guarantee to fit all requirements.
Currently, two Product Specifications are under consideration:
S-127, Marine Traffic Management
S-128, Catalogue of Nautical Products
Marine Traffic Management
The diagrams, which are related to Version 0.2, are under consideration and can be downloaded. File:S-127-0.2 AppB Application Schema.pdf
Catalogue of Nautical Products
The diagrams are curruntly under revision by the contractor. They can be provided on request.
