EDCS Approach
Leverages existing domain-specific standards
- Where applicable and useful
- International: DIGEST, IMO, IHO, ISO 19110, ISO 31-x (SI)
- National: JMCDM, UCDM
- Resolves limitations of each, as appropriate
Selected one as starting point – DIGEST FACC
- Substantially modified to overcome restrictions
- Include non-features – e.g., classifications
- Address non-map/chart environmental data
- Clean separation of syntax from semantics; flexible “groups”
- Incorporate SI-compliance
Coordinated with other ongoing standards efforts
- International
- Support incremental migration of EDCS subset to DIGEST standard as appropriate (e.g., Edition 2.x) via NIMA.
- ISO/TC 211 (19110, 19126) – Cataloging and Profiles
- National
- USIGS Conceptual Data Model (UCDM)
- Joint METOC Conceptual Data Model (JMCDM)
