This document allows you to see how S-57 objects correlate to feature classes in the maritime geodatabase. The S-57 objects are in alphabetical order. The table shows the object, its description, the feature class where the object exists as a subtype, the subtype value, and the product for which it is used. If the object is a subtype in more than one feature class, the feature classes are listed in bullets. The subtype value is listed in parentheses next to the feature class. Products are also listed in bullets if there is more than one.
An object acronym in lowercase letters is an IENC or an AML extension to IHO-approved attributes and has been created specifically for that use. The Product column also shows which AML profile the objects belong to.
Note:
IHO Transfer Standard for Digital Hydrographic Data Publication S-57 Edition 3.1 - November 2000, Appendix A - IHO Object Catalogue Chapters 1 and 2 discusses objects with S-57 attributes.
