S-101 ENC Production with CARIS HPD

This training course examines the workflow involved in creating International Hydrographic Organization (IHO) S-101 Electronic Navigational Charts (ENC) in a CARIS HPD database. It starts with a general overview of the new IHO S‐100 Universal Hydrographic Data Model Standard and IHO S‐101 ENC Product Specification. This is followed by practical hands-on exercises that: introduce basic S-101 ENC theory and concepts; outline the one-off steps to set up an existing CARIS HPD database for S-101 production; and explain the steps to create and update S-101 ENC products from S-57 features in an HPD database


Anyone interested in learning about the new IHO S-101 ENC Product Specification and understanding how to implement workflows that support creating and updating S-101 ENC products in an existing CARIS HPD database.
