  5. 5. EnviroGRIDS BlackSea• The scientific aim of the EnviroGRIDS projectwas to assemble an observation system of theBlack Sea catchment that will address severalGEO Societal Benefit Areas within a changingclimate framework.
  6. 6. Habitats• The HABITATS project focused on theadoption of INSPIRE standards through aparticipatory process to design and validateenvironmental geo-spatial data, metadata,and service specifications with Europeancitizens and businesses.
  7. 7. EnviroGRIDS Architecture
  8. 8. How to avoid it?• For end-users operating services are crucial– Availability– Quality – service / data / metadata• Preparing catalogue of „clean services“ toensure availability• First step - only WMS

  14. 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. 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. 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. 17. „Heartbeat“ protocol
  18. 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. 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
