Met Ocean DWG AgendaMet Ocean DWG Agenda

• 3 sessions: 1 Monday, 2 Wednesday, 1 shared with WCS• Various talks• Progress reports

– Conceptual Modelling– WMS IE– Portrayal

• Currently interacting and active with SWGs, DWGs– WMS, WCS, SLD/SE, O&M, CSW, SWE Common, etc– Aviation, Hydro, EDM, Coverage, Defence, etc

• (Un)Healthily busy

Conceptual Modelling Actions

Outlined plan of activity over next 12 months

• Solicit help to undertake activities identified within the plan

• Publish O&M profile for Meteorology (June 2011 - June 2012)

• Harmonize MeteorologicalFeature & WXXM2 generic weather models;

migrate harmonized model into O&M Profile for Meteorology (May 2011)

• Develop case studies conforming to (evolving) O&M profile for

Meteorology in conjunction with related projects:

• IMet-Ocean DWG & Hydrology DWG joint Interoperability Experiment,

data management relating to entire water cycle (Sep 2011 - Mar 2012)

• Relate ISO/DIS 19156 O&M to ISO 19115 Geographic Metadata

• Encoding O&M WMO Table-Driven Data Representations GRIB & BUFR

WMS IE Actions

WMS IE Servers & Clients providers:• Carbon Project

• ECMWF

• Geomatys

• HR Wallingford

• IBL/ UK Met Office

• KNMI

• Meteo-France

• NOAA/NWS,

• Norwegian Meteorological Institute

• Plymouth Marine Laboratory (UK)

• University of Reading (UK)

• UCAR,uDig Community

Some are Generic, some Met Ocean specific

OGC®

WMS IE Actions2010 June - Informal simple plugfest • No major problems (connectivity, timeouts, inconsistent response

times) • Layer Names are not always explicit• Different styles for same data on different servers (Default style not

explicit)– Good: user can easily identify the origin of the data– Bad: user might prefer consistency e.g. same colour backgrounds

• Have I got the correct TIME?• Have I got the correct Projections?

WYRIWYG “What You Request Is What You Get” WYSIWIBWAF

2011 June - Toulouse – another informal plugfest / IE• More combinations: more servers, more clients• Define validation procedure for Requests• Define performance metrics

OGC®

WMS IE Actions

Keep on testing• Not high priority for our institutions• Informal, to encourage contributions, identify what is feasible,

no time constraint … • More issues:

– animations– getFeatureInfo– correspondance between map presentation & physical value

• Define basic styles for basic parameters (WMO)• Feed twiki with experience:

OGC®

Portrayal Actions - Work in progress

• Make Met Ocean Symbologies & Layer Styles easily available – WMO Secretariat & Chair of relevant Expert Team agreed

– Started comprehensive examples of WMO weather symbols (

– ~400 GIFs SVGs (120 on Wikimedia, 280 to go)

• Formalise WMO point / line / area styles, with Use Cases• Help WMO establish formal digital ownership of the styles

(registries, audit trail, etc)• Create sample registry, with authoritative textual definitions• Contribute to Portrayal and SLD/SE roadmaps, with Met Ocean

priorities• Engage other communities: DGIWG, EGOWS, WMO, ISO• Excluded some work – out of scope or too soon

More volunteers!

IssuesIssues

• Need CRS SWG resuscitated

• Concerns about OWS Common - GetCapabilities/Filter

• Doing our own community based, more informal, IEs (no IPR, no money)

• Our community standards documents (Non-OGC) not readily accessible like OGC ones
