Create a meteorological & oceanographic SDI in
Galicia
Structure and spread

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
metadata
updates the references to the last
data in the GeoPortal
Sensors network spread over Galicia
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 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
