_________________________________________________________________________ CEOS/ISPRS Workshop on Rad/Geo Cal December 3, 2003 in Gulfport, MS, U.S.A. Overview 1.Role of ISO 2.Role of ISO/TC Projects in ISO/TC Sensor and data models for imagery and gridded data (ISO 19130) 5.Other imagery projects in ISO/TC 211

_________________________________________________________________________ CEOS/ISPRS Workshop on Rad/Geo Cal December 3, 2003 in Gulfport, MS, U.S.A. 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

_________________________________________________________________________ CEOS/ISPRS Workshop on Rad/Geo Cal December 3, 2003 in Gulfport, MS, U.S.A. 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

_________________________________________________________________________ CEOS/ISPRS Workshop on Rad/Geo Cal December 3, 2003 in Gulfport, MS, U.S.A. 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.)

_________________________________________________________________________ CEOS/ISPRS Workshop on Rad/Geo Cal December 3, 2003 in Gulfport, MS, U.S.A. 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 to ISO Geographic information is a spezialization of computer science. Photogrammetry and remote sensing are a subtopic of geographic information.
