INSPIRE Conference 2011 – Edinburgh, June 30METEOSIX – BUILDING A METEOROLOGICAL SDI FOR THE REGION OF GALICIA (SPAIN)*Xurxo Méndez, Juan Touriño, Jorge Parapar, Marcos Hermida, Vanesa García, Manuel Antonio Regueiro, José Ramón Viqueira, Francisco Landeira * Project founded by the Galician Government (code: 09MDS034522PR) http://meteosix.cesga.es Computer Architecture Systems Group Laboratory (University of A Coruña) MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

Outline● Context: ● Meteorological and oceanographic data ● INSPIRE and Spanish transposition ● MeteoGalicias systems and workflow● MeteoSIX goals● MeteoSIX global architecture● The challenges: ● The data representation matter ● Rapid varying data ● The SOS problem● MeteoSIX and the community● Roadmap 3 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

Context● Great importance of Meteorological information ● Daily management of wind and solar power stations ● Control of pollution emissions ● Agricultural and fishing resources administration ● Personal trip planning ● …● Increase of the amount of collected and generated information● Improvements in the technical means 4 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

Context● INSPIRE ● Annex III mentions – ”13. Atmospheric conditions” (measurements, models...) – ”14. Meteorological geographical features” (temperature, precipitation, wind speed and direction...) – ”15. Oceanographic geographical features” (salinity, wave height...)● Spanish INSPIRE transposition ● LISIGE (Law 14/2010, July 5th) – Keeps the same points 5 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

Context● Works dont start from scratch ● Common Data Model ● NetCDF ● OPeNDAP ● WCS ● SLD ● SWE ● ... 6 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

Context● Where is Galicia? Galicia Santiago de Compostela * photo of the cathedral of Santiago de Compostela by adamrice 7 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

Context● MeteoGalicias systems and workflow ● Organization responsible for obtaining and spreading meteorological information in Galicia http://www.meteogalicia.es ● Complex observation system, with networks for – 100+ weather stations – Marine data – Lightning detection – Radar data – Satellite data and imagery – ... 8 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

Context● MeteoGalicias systems and workflow ● Several numeric forecasting models – WRF – WW3 – SWAN Finisterrae Supercomputer – MOHID 2500 64bit CPUs – … 19K GB RAM … that run on different grids in the Finisterrae supercomputer, at CESGA (Galician Supercomputing Center) 9 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

MeteoSIX goals● Create a meteorological & oceanographic SDI in Galicia● Structure and spread ➔ Available forecasting geoinformation ➔ Available observation geoinformation … using ● OGC services: – WMS, WFS, WCS, SOS ● Non-OGC services: – NetCDF Subset, OPeNDAP... 10 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

MeteoSIX goals● Elaborate a GeoPortal that lets ➔ the general public ➔ MeteoGalicias forecasting staff … to ➔ discover ➔ query ➔ view ➔ download … those data 11 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

MeteoSIX global architecture GeoPortal GeoPortal DB Apache PostgreSQL Wicket User WMS, WCS, SOS, NetCDF Subset Forecast Data Data Servers Observations DB Models executions results SQL Server SOS Server Complementary Forecast in CDM-complaint files 52North- Server Server (NetCDF, Grib, HDF...)GPRS, ethernet,ssh, satellite, based GeoServer THREDDSradiofrequency Sensors Numerical Generic DB Finisterrae {Meteorological PostGIS models input supercomputer stations, platform buoys, coast (CESGA) buoys, water stations, Data from GFS, mareographs, WRF, WW3, radiosondes...} ESEOAT... 12 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

The challenges● The data representation matter ● WMS and WFS were not designed to deal with meteorological data – Issues when ● managing vertical and temporal dimensions ● managing styles ● … Representation of ”wind” variable 13 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

The challenges● Rapid varying data ● Numerical forecasting models generate new data twice a day ● Sensors continuously produce new observations ● User needs the last available data ➔ Implementation of a polling system that • reads and interprets the services Sensors network spread over Galicia metadata • updates the references to the last data in the GeoPortal 14 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

The challenges● The SOS problem ● Four different types of sensors – In-situ – Remote – Static – Mobile ✔ The standard (SOS) contemplates this ✗ Current available solutions do not support all those types 15 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

The challenges● The SOS problem ● Data integration technologies have to be developed to provide a uniform SOS data access interface to a heterogeneous collection of meteorological and oceanographic legacy data sources 16 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

MeteoSIX and the community● Some code contributions have already been made ● In OpenLayers, some patches improving SOS support ● In ncWMS – Contributions enabling the server to read and display data in different projections – Some synchronization issues fixed 17 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

Roadmap● Initial version (September 2011) ● Layers overlay 18 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

Roadmap● Initial version (September 2011) ● Georeferenced queries 19 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

Roadmap● Initial version (September 2011) ● Favourite locations 20 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

Roadmap● Initial version (September 2011) ● Different roles Normal users data view Advanced users data view Aministrator interface 21 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)

Roadmap● For the final release (December 2012): ● Syndication system (GeoRSS) – For any location – For users favourite locations ● Mobile version of the site ● Statistics ● Vertical cross-sections graphics ● Temporal animations ● History ● ...● Give feedback to the communities ● Suitability of data formats ● Performance of protocols 22 MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)
