1 INSPIRE implementation as a link between egovernment and environmental purposes Jiří Poláček Czech Office for Surveying, Mapping and Cadastre (ČÚZK)

2 Agenda Role of ČÚZK branch in the INSPIRE implementation. What are we running and how we do it. Specific conditions for INSPIRE implementation at our office. Experience with running free on-line services. Use-cases of the existing network services. Stránka 2

4 Source Information Systems for specific INSPIRE themes ČÚZK Information System of Cadastre of Real Estates (ISKN) Basic Register of Territorial Identification, Addresses and Real Estates (RÚIAN) Buildings, Addresses, Administrative units Cadastral parcels Land Survey Office (ZÚ) Hydrography, The Fundamental Base of Geographic Data (ZABAGED) Transport networks, Protected sites, Land cover Geographical names Database Orthoimagery of geographic names (Geonames) Ortoimagery of the Czech Republic Altimetry INSPIRE Conference 2017 New Altimetry of the Czech Republic Stránka 4

8 What Are We Running INSPIRE harmonized services: View : Cadastral Parcels (since 2011), Addresses, Administrative Units (since 2013), Buildings (since 2015) Download: Cadastral Parcels (since 2012), Addresses, Administrative Units (since 2013), Buildings (since 2015) Both WFS and pre-prepared datasets (GML 3.2.1) ATOM for pre-prepared datasets National services: View service for the cadastral map (including the raster map - since 2008) National extensions for the AU, AD and CP themes Stránka 8

9 Specific situation of ČÚZK On-line Source information systems are run on-line, data is frequently updated. Need for making decision in external egovernmental Agendas. Open RÚIAN data is Open Data by law. INSPIRE download services for mentioned themes (subset of RÚIAN data) are available for free. Digital Cadastral Maps are available for free. Need of early Implementation RÚIAN was a newly established database. Duty to harmonize data and run harmonized download services in strict terms (2012 for Annex I, 2015 for Annex III).

12 Side Effects of the On-line Solution Bright side: On-line services (especially WMS) are used by a number of applications (both internal and external) As no registration is required, they are easy to use Dark side: It is not possible to guarantee availability and responses for free services and applications Most of our users are anonymous Difficulties with edge-matching on the state borders Stránka 12

13 Operational Aspects Occasionally system load suddenly increases Serious obstacles has been caused mainly by the Viewing Cadastre application The most serious cases: March 2008 January 2014 Stránka 13

17 Use-cases (How to search use-cases of anonymous users?) Generally we get IP addresses only. Some applications contain links to the web pages, from which our network services were accessed. During July 2017 more than 1 thousand such pages were monitored. Following use-cases are based on this list (selected open applications). Stránka 17

31 Conclusion Operational run: Long-term experience with the operational run (WMS launched in March 2008). Running free and on-line INSPIRE network services brings specific challenge, it is difficult to use free services for guaranted applications. The real need of view services is much higher than the defined INSPIRE parameters. Implementation: Data harmonization and network services for the INSPIRE themes under our responsibility has been succesfully completed. Great number of free applications has been developed using these network services. INSPIRE implementation has not been considered as an obstacle but as a chance to build up infrastructure for providing spatial data with respect to the end-user needs. Stránka 31
