Introduction

An S-100 based Product Specification defines a data product, and usually includes additional resources such as a machine readable Feature Catalogue and Portrayal Catalogue, a data Encoding Guide and at lease one data encoding format. The S-100 Working Group (S-100WG) are developing draft guidance documents for developing Product Specifications, which can be downloaded from the Miscellaneous section of the S-100WG page.

The following is a list of S-100 based Products Specifications that are published; currently under development; or planned for development. Links to published versions of the Product Specifications in the Product Specification Register within the IHO GI Registry are included; as well as links to the relevant Product Specification development sites, where available:
