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.

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.

EnviroGRIDS Architecture

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

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

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

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

„Heartbeat“ protocol

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 %)

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
