2. What? Why?
Finnish Meteorological Institute is
opening weather data it owns:
• Real time observations
• Forecast models
• And more…
Countless opportunities to build
new apps and services with weather
data.
• Weather impacts each and
everyone.
• Many fields and activities are
affected by weather
• Pure weather apps or weather
integrated to apps

3. Content
Data is opened in phases:
• First sets available by summer 2013
• New sets will be added during 2013-2014
Data sets can be categorized into three types:
• Real time observation
• Latest observations from the area,
weather radars…
• Observation time series
• Long time series from some point(s)
• Forecast models
• Time series to a single point or binary
encoded grid data

7. Open Data Interface
FMI open data portal is designed to
meet INSPIRE requirements
• Catalog (CSW) provides a high
level catalog.
• View Service (WMS) shows the
data as an example.
• Download Service (WFS 2.0)
provides the data in GML
(Geography Markup Language)
encoded form.
• For large data sets as weather
forecast model WFS provides a
GML envelope with a link to the
binary encoded data.

8. Open Data Interface
• O&M (Observation & Measurement)
standard is honored.
• Data format is optimized for data
exchange and interoperability.
• Interoperability in INSPIRE means
the possibility to combine spatial
data and services from different
sources across the European
Community in a consistent way.
• And there will be much data
available in next few years,
take a look:

eb/fi/kansallinen-aineistoluettelo
• http://inspire.jrc.ec.europa.eu

9. Open Data Interface
Registration will be required for open
data portal.
• The user will get an API Key.
• Transactions will be limited based
on the API Key.
• Catalog (CSW) will be open
• Download Service (WFS) have
loose limits
• View Service (WMS) have quite
strict limits

10. Open Data Interface
So.. WMS is just for browsing the data.
• If you want provide maps in your
applications, you have to download
the data and create your own WMS.
WFS transaction limits are designed so
that
• You should be able to download
almost as much data as you want
into your server.
• But applications with lots of end
users can not rely directly on FMI
WFS.
Possibility to purchase unlimited
access to the data.

11. Libraries
FMI is also going to publish an open
source library ’MetO Lib’ to help loading
and handling data.
• First JavaScript
• Next some scripting language, but
what?
• Python?
• PHP?
Some sample client implementations
are going to be published as well.

12. When
The portal is published by summer
2013.
• Beta version opens in February.
• Beta version will contain some data
but its content and API may change
before the release date.
• Try it out! We are eager to get
feedback as soon as possible.
