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)

DIS deliverables

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

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

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

Investigating need for a standardized format for description of coordinate representation

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 locati

on representation• or within a format registry

The registry should include:– Unique identifier– Name– Version– Data elements and their types– Structure of the data

(type of separator, ...)– Compression mechanism

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

Variety of data formats/profiles used to represent/encode geographic point location in character/binary/etc.

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

Issues

• Scope:– Concentrate on 19113 & 19115– Consider other quality-related standards where re

levant

• 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
