® © 2010 Open Geospatial Consortium, Inc Met Ocean DWG Activities Questionnaire to establish issues and priorities Starting position: –WMS profile for ‘near operational’ use –Time –Vertical coordinates, layers –CRSs –Performance ‘Community’ established Last 3 months: –active debate, telecons, twiki,

® © 2010 Open Geospatial Consortium, Inc Met Ocean DWG Progress Current position: WMS –First works on time issues –working towards IEs –Use Cases being documented and refined –options for Time being documented Observations, forecasts Climatology tbd Conceptual Modelling –Use Cases being documented and refined –with WMO Expert Team led by Jeremy Tandy (IPET/MDI chair) Meteo Use Cases for SLD/SE –Aviation Significant Weather Chart –Standard WMO data representation

® © 2010 Open Geospatial Consortium, Inc Met Ocean DWG Use Case Aspects Can we share WMS and Modelling UCs? –Institutional Users versus End Users –Domain Expert vs other Expert vs non-expert cases –Mainstream vs ‘edge’ or ‘envelope breaking’ cases

® © 2010 Open Geospatial Consortium, Inc Met Ocean DWG Other Interests Catalogues –WMO prefers ISO SRU –Interoperability with CSW SLD/SE –‘Overhanging’ tile edges e.g. wind arrows –Raster vs Vector graphics WCS and binary data Payload –NetCDF and CF convention –GRIB and BUFR –Other 5 + D Hypercube vs traditional geo data models –Core and extension approach –Queries and ‘subsetting’

® © 2010 Open Geospatial Consortium, Inc Met Ocean DWG Issues Spreading too thin –Need more experts involved Need more oceanographers –with ‘seaweed under fingernails’ Timescales –Realistic vs ambitious –TIME + another time can fix WMS, WMTS enough –Layers, 5 + D conceptual model, etc for WCS, CSW, WFS, etc
