2. MIOs and SDIs An SDI encompasses the policies, technologies, standards and human resources necessary for the effective collection, management, access, delivery and utilisation of geospatial data for a specific jurisdiction or community (GSDI, 2004)

3. Marine Information Objects (MIOs) MIOs are not contained within nor are they an integral part of an ENC.MIOs are not contained within nor are they an integral part of an ENC. MIOs are separate, supplementary information that are displayed in conjunction with the overall System ENC.MIOs are separate, supplementary information that are displayed in conjunction with the overall System ENC. Similar in concept to adding radar and AIS information to an ECDIS display.Similar in concept to adding radar and AIS information to an ECDIS display.

4. Marine Information Objects (MIOs) - Chart and navigation-related information that supplement the minimum information required by IMO ECDIS Additional, non-mandatory Not covered by existing standards (e.g., IHO S-57, IHO S-52, or IEC 61174) The everything else Points, lines, areas, features, objects

11. Generic MIO Product Specification Purpose: All MIOs will be based on a single, generic MIO Product Specification. Will be similar to Additional Military Layers (AMLs) developed/used by NATO.Will be similar to Additional Military Layers (AMLs) developed/used by NATO. ENC software manufacturers will not have to develop new software tools to deal with MIOs.ENC software manufacturers will not have to develop new software tools to deal with MIOs. Existing ECDIS/ECS can read MIOs in the same manner as ENCs and AMLs.Existing ECDIS/ECS can read MIOs in the same manner as ENCs and AMLs.

12. MIO Encoding Guide Purpose: Provides detailed guidance on how specific types of MIOs are encoded. Using existing/new S-57 object classes, attributes, and attribute values: 1.Provides basis for creation 2.Describes relationship to real-world entity 3.Provides criteria for its proper use 4.Gives specific encoding examples

13. Approach will be similar to what is being used to encode Inland ENC data for rivers and inland waterways.

14. International MIO Development IHO-IEC Harmonization Group on Marine Information Objects (HGMIO) - meets once year; next meeting June 2007 at Univ. of NH Recommended Procedures for Development of MIOs (Dec 2004) - How a competent organization identifies MIO requirements - Information content for MIO category - Development of new S-57 objects & attributes - Colours and symbols (based on IHO S-52) - Test and evaluation - Production and dissemination - Regulatory requirements for use (if needed)
