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

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

ContextContext
● MeteoGalicia's systems and workflow● Organization responsible for obtaining and spreading
meteorological information in Galiciahttp://www.meteogalicia.es
● Complex observation system, with networks for– 100+ weather stations– Marine data– Lightning detection– Radar data– Satellite data and imagery– ...

ContextContext
● MeteoGalicia's systems and workflow● Several numeric forecasting models
– WRF– WW3– SWAN– MOHID– …
… that run on different grids in
the Finisterrae supercomputer, at
CESGA (Galician Supercomputing
Center)

MeteoSIX goalsMeteoSIX 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...

MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)
The challengesThe 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
14
MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)
The challengesThe 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
metadata• updates the references to the last
data in the GeoPortal
Sensors network spread over Galicia
15
MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)
The challengesThe 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
16
MeteoSIX – Building a Meteorological SDI for the Region of Galicia (Spain)
The challengesThe 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

MeteoSIX and the communityMeteoSIX 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
