OGC and IT standards


OGC formal relationships with ISO

• ISO TC 211 – Geomatics

• ISO TC 204 – Intelligent Transportation Systems

• ISO/IEC JTC1 Working Group 7 – Sensor Networks

• ISO/IEC JTC1 SC 29/WG 11 – MPEG-A (Part 13)


OGC and ISO/TC 211

• OGC is a voluntary consensus standards organisation, ISO is a de jure (by law) standards organisation

• OGC develops ‘standards’, ISO develops ‘Standards’

• OGC membership is comprised of commercial, government, research, NGO and university organisations, ISO representation is at national, country level

• The OGC is a Class A Liaison member of ISO/TC 211, this means the OGC can submit standards for processing and approval as ISO Standards


ISO TC 211 Standards /OGC Abstract Specifications

• ISO 19107: Spatial Schema is OGC AS Topic Volume 1

• ISO 19115: Metadata is OGC AS Topic Volume 2

• ISO 19119: Services is AS Topic Volume 12

• ISO 19148 Linear Referencing approved as an OGC AS Topic Volume 11


Joint Advisory Group (JAG)

• The Joint Advisory Group (JAG) comprises ISO/TC 211 and OGC members

• Meets alternately at ISO/TC 211 and OGC TC/PC meetings

• Goal of the JAG is to ensure proper and consistent communication and coordination between the OGC and ISO/TC 211


Status of joint documents June 2012 (OGC submission to ISO)

• Spatial Referencing by Coordinates [19111] AS Topic Volume 1

• Simple Features 1.1 [ISO 19125-1 and 2]

• OGC Geography Markup Language 3.2.1 [ISO 19136]

• OGC Web Map Service 1.3 [ISO 19128]

• Web Feature Service 2.0 [ISO 19142] and Filter Encoding 2.0 [ISO 19143]

• Observations and Measurements 1.0 approved as an OGC Abstract Specification Topic Volume [ISO 19156]


Standards for exchanging geospatial and temporal data in development since early 1994 through OGC and ISO/TC 211; Web services since 2000.

• ISO TC211 standards form the foundation– 19103 Conceptual schema– 19107 Spatial schema– 19108 Temporal schema– 19111 Coordinate reference– 19115 Metadata– 19123 Coverage schema

• OGC standards that implement or reference ISO standards– Web Mapping Service (WMS): simple graphic images– Web Feature Service (WFS): vector data– Web Coverage Service (WCS): gridded data– Catalog Service: portal index– Geography Markup Language (GML): XML schema and data

OGC and ISO/TC 211 overview


OGC and ISO/TC 211 example

• Air Quality Community of Practice, in conjunction with GEOSS Architecture Implementation Pilot-2 (AIP-2)

• A community catalog for air quality data to be harvested/searched by the GEOSS Clearinghouse

• Using ISO 19115/119 as a metadata framework• Using OGC WMS/WCS as initial source of metadata

for catalog records• Combination of ISO 19119, service description,

and 19115, data description • An example of how OGC and ISO standards are related• OGC WFS is also now an ISO standard 19142: 2010
