OGC Overview 2
Vision:
A world in which everyone benefits from the use of geospatial information and supporting technologies.
Mission:
global forum for collaboration of developers and users of spatial data products and services and to
advance the development of international standards for geospatial interoperability
Strategic Goals:
Goal 1 - Provide free and openly available standards to the market that are of tangible value to Members and have measurable benefits for users.
Goal 2 - Lead worldwide in the creation and establishment of standards that enable global infrastructures for delivery and integration of geospatial content and services into business and civic processes.
Goal 3 - Facilitate the adoption of open, spatially enabled reference architectures in enterprise environments worldwide.
Goal 4 - Advance standards to support formation of new and innovative markets and applications for geospatial technologies.

8. OGC: Approach to Advancing Interoperability
Interoperability Program – a global, innovative, hands-on rapid prototyping and testing program designed to unite users and industry in accelerating interface development and validation, and the delivery of interoperability to the market
Rapid Interface
Development
Standards
Setting
Specification Development Program – consensus standards process similar to other Industry consortia (World Wide Web Consortium, OMA etc.)
Compliance Testing & Certification Program – allows organizations that implement an OGC standard to test their implementations with the mandatory elements of that standard
Testing &
Certification
As a response, the OpenGIS concept and dream began due to:
1. The user’s need to integrate geographic information contained in heterogeneous data stores whose incompatible formats and data structures have prevented interoperability. This incompatibility has limited use of the technology in enterprise and Internet computing environments, and the time, cost, and expertise required for data conversion have slowed adoption of geoprocessing across all market segments.
2. The larger community’s need for improved access to public and private geodata sources, with preservation of the data’s semantics.
3. Agency and vendor needs to develop standardized approaches for specification of geoprocessing requirements for information system procurements.
4. The industry’s need to incorporate geodata and geoprocessing resources into national and enterprise information infrastructures, in order that these resources may be found and used as easily as any other network-resident data and processing resources.
5. Users’ need to preserve the value of their legacy geoprocessing systems and legacy geodata while incorporating new geoprocessing capabilities and geodata sources.

34. Challenges for OGC standards in Meteorology
Long history of interoperability at human/paper level
Spatial & Temporal, 2D, 3D, 4+D, constantly changing
Not MBytes, but GB, TB and PetaBytes of data daily.
Irregular time intervals
Timescales: hours,.., seasons,.., centuries, + & -
Multiple Time attributes
‘Regular’ grids are not always regular
Continual change of coordinate systems & projecting
Eulerian versus Lagrangian viewpoints
Vertical coordinates
Cross-sections, height-time diagrams, T/φs, etc
Ensembles: probabilistic distributions
Significant ‘Objects’, features of interest
‘Now’ T+0, not allowed in calculations in Is allowed in 19139
360 day years
Interpolation is routine and sophisticated, using a NWP, or truncation. Could be continuous or dichotomous at same time
Scalars, vectors, tensors

Extend the BP towards a Profile (+ Chair WMS SWG?)
Expand WMS1.3 BP with climatological periods, calendars, etc
Express Requirements/Change Request to WMS2.0 (now back to 1.4)
Improve weather symbols in SVG, & styles, for SLD/SE on Github
Interact more with the on Aviation DWG for Met
Influence or use other OGC standards e.g. O&M, PubSub, WPS, etc
Work on WMO Registries, Vertical & Temporal CRSs, etc

44. OGC Met Ocean DWG Summary
is becoming global, rather than American
has opened up processes to community groups
Twiki, mailing lists
is updating standards from client/server to RESTful
Is restructuring standards to a ‘Core & Extensions’ model
In middle of ‘2D+Layers’ versus ‘4D+slice & dice’ churn
Interoperability Experiments and Test beds are still heavyweight, to protect members’ IPR
Not an issue for Met Ocean community
Has taken on Met Ocean requirements in key standards, even when Met Ocean people not actively involved
More volunteers and experts needed

45. Met Ocean DWG Summary
Members: UKMO, M-F, DWD, ECWMF, EUMETSAT, FMI, KNMI, met.no, met.ro, CMC, NOAA, BoM, (JMA, KMA, ??)
WMS Time & Elevation, Ensembles Best Practices defined, being implemented
Consistency between WMO, ICAO and OGC conceptual models achieved
Work started on WCS and data payloads
Work started on temporal aspects
Non-WMO observations are increasingly important, so OGC observation standards becoming important
Interests moving out of Met Ocean DWG to other WGs
Lots of work, increasing importance – join in!
