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

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.)

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.

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
