1) The EnviroGRIDS project assembled an observation system for the Black Sea catchment area to address several environmental issues related to climate change. 2) The HABITATS project focused on adopting INSPIRE geospatial data standards through public participation to design and validate environmental data specifications. 3) The Czech Centre for Science and Society has established a Super Catalogue of Catalogues (SuperCAT) that harvests over 2,000 geospatial web services from various catalogs and registries, and monitors their availability on a daily basis.

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
