  1. Wolfgang Kresse ISPRS WG II/4 “Image data standards“

  2. Overview 1. Role of ISO 2. Role of ISO/TC 211 3. Projects in ISO/TC 211 4. Sensor and data models for imagery and gridded data (ISO 19130) 5. Other imagery projects in ISO/TC 211

  3. 1. Role of ISO (1/2) 3 international standards developing organizations ISO International Organization for Standardization (isos = equal) IEC International Electrotechnical Commission ITU International Telecommunication Union Joint Technical Committee: ISO/IEC JTC1: computer sciences

  4. 1. Role of ISO (2/2) ISO is an official organization national standardization organizations (ANSI, DIN, etc.)   external liaison members (CEOS, ISPRS, OGC, etc.) internal liaison members (other ISO committees)   about 190 Technical Committees many Working Groups, Subcommittees Fast development of a standard development within 5 years Guaranteed maintenance review of a standard at least every 5 years ISO/TC 211 is a standing committee with a guaranteed annual budget Purchase of standard documents via the Internet

  5. 2. Role of ISO/TC 211 (1/2) ISO/TC 211 “Geographic information / Geomatics” ~30 voting national members: U.S.A., Canada, Japan, China, South Korea, UK, Norway, Germany etc. ~30 observing members: mostly smaller countries ~20 external liaison members: CEOS, ISPRS, OGC, IHO (hydrography), FAO (food and agriculture), DGIWG (NATO digital mapping), etc.   ~10 internal liaison members: other ISO TCs and ISO/IEC JTC1 (car navigation, data formats HTML, VRML, BIIF etc.)

  6. 2. Role of ISO/TC 211 (2/2) 5 Working Groups (4, 6, 7, 8, 9) 40 project teams (development of one International Standard each) Numbers range ISO 19101 to ISO 19140 Geographic information is a spezialization of computer science. Photogrammetry and remote sensing are a subtopic of geographic information.

  7. 3. Projects in ISO/TC 211 (1/1) Inofficial categories of the ISO 19100 standards Infrastructure standards Basic standards Imagery standards (mostly in Working Group 6) Implementation standards

  8. 4. Sensor and data models for imagery and gridded data (ISO 19130) (1/7)

  9. 4. Sensor and data models for imagery and gridded data (ISO 19130) (2/7)

  10. 4. Sensor and data models for imagery and gridded data (ISO 19130) (3/7)

  11. 4. Sensor and data models for imagery and gridded data (ISO 19130) (4/7)

  12. 4. Sensor and data models for imagery and gridded data (ISO 19130) (5/7)

  13. 4. Sensor and data models for imagery and gridded data (ISO 19130) (6/7)

  14. 4. Sensor and data models for imagery and gridded data (ISO 19130) (7/7) Timeframe of development Approval of New Work Item Proposal in 2001 Working Draft (WD) present status Committee Draft (CD) in the beginning of 2004 Draft International Standard (DIS) planned in summer 2004 Final Draft International Standard (FDIS) planned in 2005 International Standard (IS) planned in the end of 2005

  15. 5. Other imagery projects in ISO/TC 211 (1/6) Imagery, gridded and coverage data framework (ISO 19129) Decision-support list: Necessary work-items to qualify existing ISO 19100 standards for the purpose of imagery Examples: New standard ISO 19101  ISO 19101-2 (Reference model) Amendment ISO 19117  add LUT etc. (Portrayal)

  16. 5. Other imagery projects in ISO/TC 211 (2/6) Reference model for imagery (ISO 19101-2) Core-model: ISO/IEC 10746 „Information technology – Open distributed processing – Reference model“ Computational viewpoint Information viewpoint Engineering viewpoint Enterprise viewpoint Technology viewpoint

  17. 5. Other imagery projects in ISO/TC 211 (3/6) Metadata for imagery (ISO 19115-2) ISO 19115-2 “Metadata – Part 2: Extensions for imagery and gridded data” Source catalogues for ISO 19115-2: FGDC metadata standard ASPRS Draft Standard for Aerial Photography IHO:S61 DGIWG German DIN-standards etc.

  18. 5. Other imagery projects in ISO/TC 211 (4/6) Encoding for imagery Sources: GeoTIFF ISO/IEC JTC1/Subcommittee 24 “Computer graphics and image processing” (TIFF, BIIF) Planned structure: Existing standards or de-facto standards + Environment described in XML

  19. 5. Other imagery projects in ISO/TC 211 (5/6) Calibration and validation Future topic: Integration of results of the Joint CEOS/ISPRS Task Force on Radiometric and Geometric Calibration

  20. 5. Other imagery projects in ISO/TC 211 (6/6) Coverage geometry and functions (ISO 19123) A coverage is a function to return values from its range of attributes for any position within its spatiotemporal domain. Spatiotemporal domain: 2 or 3 spatial dimensions 0 or 1 temporal dimension Attribute range: one or many attributes at each position within the spatiotemporal domain
