# ISO/TC 211 Geographic information/Geomatics

ISO/TC 211 is a standard technical committee formed within ISO, tasked with covering the areas of digital geographic information (such as used by geographic information systems) and geomatics. It is responsible for preparation of a series of International Standards and Technical Specifications numbered in the number range starting at ISO-19101. The Chair of the committee was 1994-2016: Olaf Østensen; during 2017-2018: Christina Wasström; and from 2019 Agneta Gren Engberg.

## Scope

ISO/TC 211 is concerned with the standardization in the field of digital geographic information. This work aims to establish a structured set of standards for information concerning objects or phenomena that are directly or indirectly associated with a location relative to the Earth.
Project specification areas within the ISO/TC 211 technical committee include:
* Simple Features access
* Reference models
* Spatial and temporal schemas
* Location-based services
* Metadata
* Web feature and map services
* Classification systems
The ISO/TC 211 work is closely related to the efforts of the Open Geospatial Consortium. ISO/TC 211 have numerous liaisons with other organizations that often results in identical or nearly identical standards often being adopted by both organizations.

## Working Groups

The work within ISO/TC211 is done in working groups, each with a specific focus. The currently active working groups are:
* Working Group 1 - Framework and reference model
* Working Group 4 - Geospatial services
* Working Group 6 - Imagery
* Working Group 7 - Information communities
* Working Group 9 - Information management
* Working Group10 - Ubiquitous public access
There are also a number of disbanded Working Groups:
* Working Group 2 - Geospatial data models and operators
* Working Group 3 - Geospatial data administration
* Working Group 5 - Profiles and functional standards
* Working Group 8 - Location based services
Revision of standards that were previously part of these working groups are now done directly under the TC since the disbandment of the groups.
