Introduction The S-100 Standard is a framework document that is intended for the development of digital products and services for hydrographic, maritime and GIS communities. It comprises multiple parts that are based on the geospatial standards developed by the International Organization for Standardization, Technical Committee 211 (ISO/TC211). 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 least one data encoding format. A guidance document S-97 for developing Product Specifications can be downloaded from the GI registry. A list of known IHO S-100 based product specifications is provided here.
