You are forcing me to sin, because when using the portal I always start cursing …

How to avoid it

• For end-users operating services are crucial– Availability– Quality of service / data / metadata

• Preparing catalogue of „clean services“ to ensure availability

• First step - only WMS

4 www.envirogrids.cz www.envirogrids.net

Establishment of the catalogue• 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

6 www.envirogrids.cz www.envirogrids.net

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

Service metadata

• 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

Testing services availability• If Capabilities document is available and valid• Periodically (P1D)• Not valid services are set “hidden”, not erased• Detect linkage in metadata

Testing avalability of services• Tools for service provider feedback

– RSS channel– Automatic mail notification– “Heartbeat” record

10 www.envirogrids.cz www.envirogrids.net

„Heartbeat“ protocol

11 www.envirogrids.cz www.envirogrids.net

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 %)
