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

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...)

Context
●
●
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
...

Context
●
●
Several numeric forecasting models
–

WRF
WW3
SWAN
MOHID
…
Finisterrae Supercomputer
2500 64bit CPUs
19K GB RAM
… that run on different grids in
the Finisterrae supercomputer, at
CESGA (Galician Supercomputing
Center)

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 goals
●
Elaborate a GeoPortal that lets
➔
the general public
➔
MeteoGalicia's forecasting staff
… to
➔
discover
➔
query
➔
view
➔
download
… those data

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
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
metadata
updates the references to the last
data in the GeoPortal
Sensors network spread over Galicia
14
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
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 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
Roadmap
●
Initial version (September 2011)
●
Layers overlay
18
Roadmap
●
●
Georeferenced queries

Roadmap
●
●
Different roles
Advanced users data view
Normal users data view
Aministrator interface
21
Roadmap
●
For the final release (December 2012):
●
Syndication system (GeoRSS)
–
–
●
For any location
For user's 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
