Cadastre always meets specific requirements –150 years ago as well as in the digital age

INSPIRE – SDI in EuropeInfrastructure for Spatial Information in Europe


� Came 2007 into force

� Until 2009 transposition in national law

� Aim: Existent spatial data should be made available by usingexisiting GI standards and by defining further rules

� INSPIRE also develops detailed technical implementing rulesand technical guidelines

� Not just the „infrastructure“ (web service interfaces), but also concrete data content will be provided taking into account theuser needs

COMMISSION REGULATION (EU) No 102/2011 of 4 February 2011 amending Regulation (EU) No 1089/2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of

Guidelines for Cadastral Parcels

UML Data Model


and Geoinformation

� Provide metadata elements

� Implement discovery and view services

Requirements for cadastral parcels

To be INSPIRE compliant following issues have to beaddressed:


� Implement discovery and view services

� Transform source data into INSPIRE conformant data sets

� Use the mandatory elements (ID, geometry, label, cadastralreference)

� Provide download service (WFS or predefined data sets)

� „Only“ cadastral parcels are required, no owner information

� Cadastral processes in the national systems will not change

SDI provides a lot of thematic data that often needcadastral information to support various use cases such as sustainable development

and Geoinformation

• SDI and INSPIRE will not change the basic function of cadastre; property protection is one important pillar in our society

• In the digital age cadastral parcels maintain and enhance their role as basic information for a lot of use cases (multi purpose cadastre)

• SDI and INSPIRE will change the data transfer processes

• With standardized data formats and services an easy access to

5. Conclusions

• With standardized data formats and services an easy access to cadastral information is possible

• Information about the data (actuality, resolution etc.) will help the user to analyse the data (check the fitness for purpose)

• Interoperable cadastral data (cross countries) will be possible with INSPIRE

• But: still some issues to be solved (pricing, licencing…)
