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

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 organizationnational standardization organizations (ANSI, DIN, etc.)
external liaison members (CEOS, ISPRS, OGC, etc.)internal liaison members (other ISO committees)
about 190 Technical Committeesmany Working Groups, Subcommittees
Fast development of a standarddevelopment within 5 years
Guaranteed maintenancereview of a standard at least every 5 yearsISO/TC 211 is a standing committee with a guaranteed annualbudget
Purchase of standard documents via the Internet

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 19101 to ISO 19140
Geographic information is a spezialization ofcomputer science.
Photogrammetry and remote sensing are a subtopic ofgeographic information.

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

Coverage geometry and functions (ISO 19123)
A coverage is a function to return valuesfrom its range of attributes for anyposition within its spatiotemporal domain.
Spatiotemporal domain:
2 or 3 spatial dimensions0 or 1 temporal dimension
Attribute range:
one or many attributes at each position within the spatiotemporal domain
