The document discusses the relationship between the Open Geospatial Consortium (OGC) and the International Organization for Standardization (ISO), focusing on their complementary roles in setting IT and geospatial standards. OGC develops voluntary consensus standards that are publicly available, while ISO establishes de jure standards, with both organizations working together to ensure interoperability and communication. Examples of their collaboration include standards for geospatial and temporal data, as well as specific applications like air quality data management.

2. IT standards matter
Without standards, there would be no Internet or Web:
• TCP/IP - (Transmission Control Protocol/Internet Protocol)
basic communication language of the Internet.
OGC standards are consistent with
and built on mainstream IT standards.

3. The OGC Vision
Achieve the full societal, economic and
scientific benefits of integrating location
resources into commercial and institutional
processes worldwide.

6. 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)

7. 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

8. 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

9. 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

11. OGC and ISO/TC 211 overview
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

12. 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
