Agenda
European Drought Observatory (EDO)
http://edo.jrc.ec.europa.eu
EDO provides:
• Continental overview of
information on drought
• Visualization and analysis
• Seamless access to
regional and national
drought information
Geographical information system (GIS)
• system designed to capture, store, manipulate, analyze,
manage and visualize all types of geographical data
Raster (map of drought index)
Geographical information system (GIS)
Geographical information system (GIS)
Vector
– Points (drought index on
the stations)
– Lines or polylines
– Polygons (drought index
for regions)
Geographical information system (GIS)
Geographical information system (GIS)
Vector -> raster: interpolation (different types of kriging)
Output: special formats (include information about coordinate
system, resolution, boundaries)
Every software for plotting maps is a kind of GIS -> output
can be saved to GIS file format
JPEG: world file

Implementation
Introduction - INSPIRE, EUROGEOSS • INSPIRE is an EU initiative to establish an infrastructure for spatial
information in Europe
• EuroGEOSS was an FP7 project that demonstrated the added value
to the scientific community and society of making existing systems and
applications interoperable and used within the GEOSS and INSPIRE
frameworks
• EuroGEOSS developed a European Drought Observatory.
• Benefits from EuroGEOSS project
– Provide a central repository of drought relevant metadata that can
be accessed by everyone over the Internet.
– A place for data producers to publish their data and data
consumers to find the data
– New services, interoperability
Drought metadata catalogue
• Information about drought
– data (raster or vector)
– links to documents (field
reports, bulletins …)
– national web pages
providing drought
information
• Realtime or near-realtime
• Climatological
Obligatory
Drought metadata catalogue – metadata Metadata
• "data about data”
• descriptive metadata: data providing information about of the data with
standard language
• Indicator name, indicator description, organization, availability …
Metadata Catalogue
• Service that stores metada
• We can easily browse summary of all data
• Other users/organization/companies can also find our data if
catalogues are publicly available
• Essential to enable interoperability
Drought metadata catalogue – needed data • Organization
– Name of the organization responsible for the indicator
– Contact (e-mail)
• Indicator name
• Indicator description
– How is the indicator created? By the application of a software?
Which? Manually? Automatically through a spatial model or GIS
analysis?
– How the component was assessed: Monitored, Calculated,
Estimated.
– What is calibration period?
– What is the frequency of updating information?
Drought metadata catalogue – needed data • Availability of information
– Is the information available to the public?
– If so, references, hyperlinks, …
• Data Range Available
– Indicate the range of data from which information is available
• Geographic extent
• Keywords
– Type of drought
• Which is the type of drought that the indicator assesses?
– ...
List of keywords will be provided.
Drought metadata catalogue - SW • XML (Extensible Markup Language) file
