OGC MDWG

A Little Background


OGC Meteo DWG: Why?

Nov 2007: ECMWF 11th Workshop on Meteorological Operational Systems - recommended:

Nov 2008: ECMWF-OGC Workshop on Use of GIS/OGC Standards in Meteorology Aims: Review use of OGC (Open Geospatial Consortium)

standards in Europe & worldwide

Promote collaboration between met services to define common standards for interoperability


Ready-made community of interest


ECMWF-OGC Workshop 2008 - 1

Topics:• Standards: OGC, WMO & Inspire representatives

• Commercial solutions

• Developments at several NMSs worldwide

• Progress elsewhere, such as ESA & Eurocontrol

Four Working Groups:• Roadmap for Collaboration

• Use of the OGC Web Map Services

• Use of GML & Coverages

• Security and Access Control


ECMWF-OGC Workshop 2008 - 2Roadmap for Collaboration

• Establish OGC Meteorology DWG• Collaboration tools, like website• 6 monthly Interoperability Experiments• Validate standards and best practices

Use of the OGC WMS

• Develop meteorological profile

Use of GML & Coverages• Develop core models, use case driven, • Validate, establish governance, registries

Security and Access Control• Delegate to proxies• Use lower level SSL/VPN IP filtering• Role based authentication• Establish Virtual Organisations


ECMWF-OGC Workshop 2007 - 3

Recommended:• Roadmap for further collaboration

• Interoperability test beds of OGC web services for met. data & visualization

• Leading to recommendations to WMO

OGC How?

TC - Technical Conference every 3 months- Boston June 2009

- Darmstadt Sept 2009

- Mountainview Dec 2009

SWG - Standards Working Groups- Fast track to ISO

DWD - Domain Working Groups- Cross-cutting

IE – Interoperability Experiments-6 monthly cycle

Management structure, OAB, open & closed


OGC What?

OGC Discussion papersOGC Best PracticesOGC Standards:

• GML Geographical Mark-up Language

• WFS Web Feature Service

• WMS Web Map Service

• Etc

Then ISO Standards:• 191xx

• Etc

Then WMO uses them, willing or not (Inspire)


OGC TC Athens March 2009 - 1

Formally established:HDWG - Hydrology Domain Working GroupMDWG - Meteorology Domain Working Group

Coordinated by: ESSDWG – Earth & Space Science DWG

MDWG Co-Chairs:Chris Little & Marie-Françoise Voidrot


OGC TC Athens March 2009 - 2

Meteo Domain WG Charter

Started formal MoU between OGC & WMO

Open Mailing list• [email protected]

• https://lists.opengeospatial.org/mailman/listinfo/meteo.dwg

Open Twiki


OGC – WMO MoU - 1

WMO benefits:• Fast, effective, user-driven process• Develop, test, demonstrate, promote standards• Visibility & accountability • Interoperability expertise• Web-based tools and practices supporting

consensus-based standards development• Ecosystem of tool-builders, researchers, small

companies, large geospatial software houses.


OGC – WMO MoU - 2

OGC benefits:• Rigorous testing on a wide variety of data:

• in-situ & mobile platforms

• active & passive remote sensing

• gridded simulations

• Web Map Services

• Develop profiling methodology• Maturation of harmonization/dependencies

methodology for global Spatial Data Infrastructures
