9. WG9 discussed this Quality Harmonization here Summary of the PT Meeting in Montreal Make a review summary to clarify what are the problems –Made an outline of the report and a schedule (too ambitious…) Possible NWIP(s) when the problems are identified WG9 Meeting in Orlando Ralf Lindgren reported the status and discussions were made. Conlusions of this meeting: Project Leader will make the first draft The draft will be sent to the members for comments Possible recommendations may be –Revise ISO 19113:2002 for 5-year revision process –Search for possible coordination with related documents such as ISO 19114:2003 (Cor 1:2005) and ISO/TS 19138:2006(?), etc.

11. WI 19145 Scope Out of scope –Definition of encoding rules and formats –Coordinate reference systems (CRS) and associated issues (e.g. units) In the scope –Explore and investigate the relevance of a registry of formats (e.g. physical data representations) or profiles for the purpose interoperability of representation of geographic point location by coordinates –Explore the content of such a registry and requirements about its structure –Catalogue potential formats and format profiles that are eventual candidates for registration –Explore potential registry owners and managers
