Aims• Professional Viewing Service• Interactive browse directly from data• Standards compliant

– INSPIRE, Open Geospatial Consortium (OGC) – GIS System

• Backwards compatible with Mersea Info system (OpenDAP)

• Eventually usable for both Products and Data• Use Viewing Service to Standardise EuroMISS?• Extend Viewing to Validation service within

EuroDESS


Prototype WP8 Viewing Service

• Based on Reading e-Science Centre Godiva2 project, adopted as Mersea Dynamic Quick View DQV– OGC Website of the month Jan2008

http://www.opengeospatial.org/pressroom/newsletters

• Key Technology: ncWMS => 2D map tiles from NetCDF files or OpenDAP servers

• ncWMS currently being incorporated into THREDDS• Uses OpenLayers for Portal

– OpenSource version of Google Maps

• Generate KML/KMZ for Google Earth downloads

Scope/Use of Viewing Service

• Browse Service for Scientists– Extensions for sections, in situ, and multi-plot displays– Stop where Ferret and Matlab take over

• Browse Service prior to data Download– For Scientific, Government and Commercial users

• Potential Validation tools and as simple input to EuroDESS or downstream services– GIS capabilities of WMS/WFS

• Incentive for, and test of, standards compliance– eg. UK Met Office use as quick browse tool


Towards Validation Services

• Model – Model comparisons• Model – Data comparisons• GIS layers for Decision Support tools (WP9)

How to proceed

• Data Standards– CF compliant NetCDF for gridded data (well defined standard)

• Data Serving Technology– OpenDAP and THREDDS (Mersea legacy) for grids (1 page

document)– Security options

• Then contact me in Reading for Viewing tests– [email protected]

• Prototype Viewing Service now– www.resc.reading.ac.uk/ecoop– Feedback on improving viewing service very welcome

• Target to establish all data feeds for TOP Month 24

Who provides

Model products?

In situ data?

Are there any more groups providing Data to EuroMISS? Ireland, Italy, Greece, Norway?

How do these data providers link to EuroMISS?

Do we have natural set of ROOS centres?
