1. WEND Update

2. WENDWG 3 3rd Meeting held May 13-14, 2013
Guidelines for the implementation of the WEND Principles
ENC Issues (Gaps, Overlaps, and Poor Quality Source Data
Development of an IHO RENC/WENC
Definition of a Cartographic Boundary

3. Revised WEND Guidelines
Approved by the WENDwg and by IRCC5
Includes procedures for the RHCs to identify and resolve ENC overlaps
Raises awareness for navigationally significant overlaps
RHC has a large coordinating role
Next steps:
IHO CL for Member State Approval as a Technical Resolution

4. ENC Issues
RHCs invited to validate the draft coverage audit provided by the UKHO and provide feedback to WEND by 31 December 2013
Acknowledged that it may not be possible to solve overlaps
Hydrographic Offices should work to make them identical

5. Development of a IHO WENC/RENC
Work is still progressing to further define the concept
Development of minimum RENC standards and procedures
Audit RENCs against the minimum standards

6. Definition of a Cartographic Boundary
EAHC proposed that there be definition of a Cartographic Boundary
Cartographic Boundary can be defined as an agreed limit to clip overlapping nautical charts or related data between two neighboring countries. The boundary shall not be signified or regarded as a political or jurisdictional boundary. It should be as simple as possible so both data compiler and the data user will be provided with most coherent service possible”.
Agreed in principle by IRCC
IHB to find a harmonized definition for Cartographic Boundary and submit it as a proposal to include it as an appendix to the WEND Guidelines
