  1. WG9 Report ISO/TC211 Plenary Meeting Montreal, Canada 2005-09-15

  2. WG9 Information Management 6 Work Items (5 finished, 1 active) • WI 6709 Standard representation of geographic point location by coordinates • WI 19127 Geodetic codes and parameters • WI 19131 Data product specification • WI 19135 Procedures for registration of geographical information items • WI 19138 Data quality measures • WI 19113 & 19115 Amendments (Stage 0), `Quality Harmonization’ • Convenor: Hiroshi Imai • WG9 Meetings • 1st Bangkok (2002-05), 2nd Gyeongju (2002-11),3rd Thun (2003-05), 4th Berlin (2003-10),5th Kuala Lumpur (2004-05), 6th Pallanza (2004-10), 7th Stockholm (2005-06) • 8th Montreal, 2005-09-13, 16:00-17:00

  3. ISO, ISO/TS deliverables ISO/TS 19127:2005 Geodetic codes and parameters • Project Leader: Julie Binder Maitra • 2005-06-23, published! • Call for Registration Authority!To be discussed later in this Plenary ISO 19135:200X Procedures for registration of geographical information items • Project Leader: Charles Roswell • Text for IS was sent to ISO in 2005-04 (N1788)

  4. DIS deliverables ISO/DIS 19131 Data product specification • Project Leader: João de Matos • Editor: Robert Walker • Target date for ballot: 2005-10-27

  5. WI19138 Data Quality Measures • Project Leader: Gerhard Joos • Editor: Erik Stenborg • Target: Technical Specification, TS • Current status: • Result of DTS Vote, N1769 (16 Yes, 2 No (US, UK), 2 Abstain, 2 not voted) • Editing Committee Meeting: • 2005-06-07/08, Stockholm • Almost done; polish up UML diagrams, and, when approved by EC members, send it for 6-week review by MBs, and then issue it as TS

  6. WI 6709 Standard representation of geographic point location by coordinates • Project Leader: Kevin Kirby • Editor: Larry Hothem • Target: IS (revision of ISO 6709:1983) • Current Status: • Result of CD Vote: N1821(14 Yes, 3 No (Denmark, Japan, Korea)) • Editing Committee Meeting • 2005-06-06/08, Stockholm • Almost done. After getting confirmation by EC members, send it to TC for 6-week review by MBs before issuing it as DIS • One possible NWIP related to this project

  7. Partial List: ISO 6709:1983 GML and other XML flavor Compact text encoding of latitude/longitude coordinates (Microsoft) SHAPE (ESRI) DGN VPF DXF MID/MIF E00 DLG and so on... Each represents geographic point location by coordinates differently ⇒ Transformation for interoperability ⇒ Need the format of geographic location The encoding format should be either within the geographic location representation or withinaformat registry The registry should include: Unique identifier Name Version Data elements and their types Structure of the data (type of separator, ...) Compression mechanism Investigating need for a standardized format for description of coordinate representation Variety of data formats/profiles used to represent/encode geographic point location in character/binary/etc. Investigate the potential demand for such a format registry with reviewing relevant issues Draft NWIP as a Stage 0 Project will be issued from WG9

  8. WI 19113 & 19115 Amendments(Quality Harmonization Project) • Project Leader: Erik Stenborg • Editor: David Danko • Type: Pleliminary Work (Stage 0 Project) • NWI ballot result in N1819 (2005-05-13) • Revised result of voting on document N 1770 New work item proposal (stage 0): Amendment to ISO 19113:2002 Geographic information - Quality principles and ISO 19115:2003 Geographic information – Metadata • 19 Yes, 2 No • Approved as a Stage 0 Project (Resolution 320) in Stockholm • 24 Experts nominated by MBs + 10 more • Meetings: • Adhoc meeting in Stockholm, 2005-06 • 1st meeting in Montreal, 2005-09-12/13

  9. Issues • Scope: • Concentrate on 19113 & 19115 • Consider other quality-related standards where relevant • Agreed to making a review summary to clarify what are the problems • Made an outline of the report and a schedule • Possible NWIP(s) may be submitted when the problems are identified in the report

  10. Issues to be covered in the report Data quality issues • References: 19104, 19109, 19113, 19114, 19115, 19115:2, 19123, 19124, 19129, 19130, 19131, 19138, 9000, N1770, N1819, JTC 1 SC-24, SC-29 • Comments to TC 211 quality standards (Erik Stenborg) • Data quality elements and data quality subelements (Erik Stenborg) • Quality concepts (Erik Stenborg) • UML-model harmonisation (Gerhard Joos) • Standardisation of semantics, taxonomy and ontology related to data quality (Norm Andersen) • Feature and attribute level quality (reporting quality for single instances). Link between quality requirements and 19109 (Dave Wesloh) • Temporal accuracy (Charles Roswell) • Imagery and sensor quality (Norm Andersen)

  11. Schedule for the Quality harmonisation project team

  12. WG9 Future Issues • Currently, one active Work Item • Depending on its review summary,possible NWIP(s) may be made related to quality harmonization • Other Possible New Work Item Proposal • NWIP related to 6709 • Registry of coordinate representation as a Stage 0 Project (first make a Draft NWIP)
