5. EnviroGRIDS BlackSea
• The scientific aim of the EnviroGRIDS project
was to assemble an observation system of the
Black Sea catchment that will address several
GEO Societal Benefit Areas within a changing
climate framework.

6. Habitats
• The HABITATS project focused on the
adoption of INSPIRE standards through a
participatory process to design and validate
environmental geo-spatial data, metadata,
and service specifications with European
citizens and businesses.

7. EnviroGRIDS Architecture

8. How to avoid it?
• For end-users operating services are crucial
– Availability
– Quality – service / data / metadata
• Preparing catalogue of „clean services“ to
ensure availability
• First step - only WMS

14. Establishment of the SuperCAT
• Harvesting existing catalogues
• Catalogues CSW 2.0.2 ISO AP 1.0
• Only services (type=service)
• Periodically (P1D)
• Sources
– GEOSS registry
– INSPIRE geoportal
– Catalogues we know about
• Problems
– No central catalogue / we don’t know about services
– Classical search engines did not succeed
– Many catalogues do not response

15. Harvested catalogues
• ISPIRE national nodes: Austria, Belgium, Czech republic, Finland,
France, Germany, Luxembourg, Poland, Portugal, Slovakia,
United Kingdom
• CIDP
• EEA SDI
• ENVIROGRIDS
• EuroGEOSS
• GEOSS
• Habitats
• One Geology Europe
• Plan4all
• WHO

16. Testing services availability
• If Capabilities document is available and valid
• Periodically (P1D)
• Not valid services are set “hidden”, not erased
• Tools for service provider feedback
– RSS channel
– Automatic mail notification
– “Heartbeat” record

17. „Heartbeat“ protocol

18. Results
• 2222 services harvested
• serviceType (all / valid)
– WMS = 96 / 88
– OGC:WMS = 1418 / 1351
– view = 343 / 190
– View = 1 / 1
– VIEW = 2 / 2
– View Service = 76 / 76
• All WMS : 1860 / 1632 (87 %)

19. Problems
– poor service metadata (missing abstract etc.)
– viewer or web page address instead of service
– no mandatory thematic classification in INSPIRE
– operatesOn broken links
– serviceType not clear
