  7. 7. the Competitiveness and Innovation framework Programme (CIP) ICT Policy Support Programme (PSP) Call 6 Grant 325140 EUROPEAN LOCATION FRAMEWORK Pan-European Reference Datasets 28 August, 2013 Reference Datasets Harmonisation Data models Reference data EuroGlobalMap 1:1 000 000 EuroBoundaryMap 1:100 000 EuroDEMEuroRegionalMap 1: 250 000
  8. 8. the Competitiveness and Innovation framework Programme (CIP) ICT Policy Support Programme (PSP) Call 6 Grant 325140 EUROPEAN LOCATION FRAMEWORK Why automation of DQ validation? Change in how geo-information is produced and consumed for variety of purposes broad range of consumers Multiple sources including VGI Data models more complex Reference geo-information needs quality (authoriative data) INSPIRE directive of the EU(2007) Annex I, II Connecting reference information to other information Linked Open Data Need for provision of cost/time effective and standardised framework to measure and improve quality Meeting the changed needs Increase of users’ trust 28 August, 2013
  9. 9. the Competitiveness and Innovation framework Programme (CIP) ICT Policy Support Programme (PSP) Call 6 Grant 325140 EUROPEAN LOCATION FRAMEWORK Data Quality Management Three approaches Data Centric -> evaluating quality (ISO 19157 and ESDIN) Process Centric -> evaluating capability (ISO 19158) User Centric approach -> creating trust -> authorative sources , usability evaluation -> ELF 28 August, 2013
  10. 10. the Competitiveness and Innovation framework Programme (CIP) ICT Policy Support Programme (PSP) Call 6 Grant 325140 EUROPEAN LOCATION FRAMEWORK ESDIN Metadata and Quality guidelines 28 August, 2013
  11. 11. the Competitiveness and Innovation framework Programme (CIP) ICT Policy Support Programme (PSP) Call 6 Grant 325140 EUROPEAN LOCATION FRAMEWORK Automatic DQ - Pilot Implementation 28 August, 2013
  12. 12. the Competitiveness and Innovation framework Programme (CIP) ICT Policy Support Programme (PSP) Call 6 Grant 325140 EUROPEAN LOCATION FRAMEWORK Quality reports 28 August, 2013 Reports (Excel) Mark-ups (Shapefiles) Info Title sheet (with information about the rules for Hydro) Comply features that fail the ‘comply’ rule set Comply summary of the high-level statistics for o the whole dataset, o class by class, o rule by rule basis. Aspire features that fail the ‘aspire’ rule set Aspire Same as above for desirable ‘aspire’ data quality rules Vertex features that fail the specific rule for minimum vertex distance Profiles set of tables relating to specific data characteristic distributions on specific classes, on the frequency of values across the data Xborder (for Trans) highlighting where data is not consistent across state borders
  13. 13. the Competitiveness and Innovation framework Programme (CIP) ICT Policy Support Programme (PSP) Call 6 Grant 325140 EUROPEAN LOCATION FRAMEWORK Quality metrics (1) The “obj Count” column gives the number of features checked The “No. Fail” column gives the number of feature that have failed the rule(s) The “% pass” column gives the percentage of conformance regarding the rule, feature class or the whole dataset. 28 August, 2013
  14. 14. the Competitiveness and Innovation framework Programme (CIP) ICT Policy Support Programme (PSP) Call 6 Grant 325140 EUROPEAN LOCATION FRAMEWORK Quality metrics (2) By feature class 28 August, 2013
  15. 15. the Competitiveness and Innovation framework Programme (CIP) ICT Policy Support Programme (PSP) Call 6 Grant 325140 EUROPEAN LOCATION FRAMEWORK Error Mark-up Layers 28 August, 2013
  16. 16. the Competitiveness and Innovation framework Programme (CIP) ICT Policy Support Programme (PSP) Call 6 Grant 325140 EUROPEAN LOCATION FRAMEWORK Benefits and Challenges Key benefits Broadening scope of existing validation process for ERM Providing measures for usability evaluation Make informed qualitative assertions on the dataset quality and between national contributions Challenges Aggregation where measurements at different scales and units Aggregation for inhomogeneous data Reporting details  DQ for producers vs. Users  DQ requirements vs. recommendations 28 August, 2013
  17. 17. the Competitiveness and Innovation framework Programme (CIP) ICT Policy Support Programme (PSP) Call 6 Grant 325140 EUROPEAN LOCATION FRAMEWORK Next Steps for E.L.F. Deploy Automatic DQ Process and Rules to Cloud-based Service Environment Easy access to commonly agreed rule sets for ELF Consistent assessment across multiple datasets Assist in provision of homogeneous data content Define User-Centric Measures for an end user application For example, establish key data measures needed to assure confidence in the data that will be used to determine risk scores in natural catastrophe risk assessment applications for insurance. 28 August, 2013
  18. 18. the Competitiveness and Innovation framework Programme (CIP) ICT Policy Support Programme (PSP) Call 6 Grant 325140 EUROPEAN LOCATION FRAMEWORK Conclusions There is a need to introduce a better management of quality for reference data Government policies are key driver for the reference geo-information (Open Data, INSPIRE, European Location Framework) Cost effectiveness is important -> automation of quality evaluation is a prerequisite User demands > creating trust -> need for authorativiness, accreditation (ISO 19158) Quality Automation based on ELF will decrease production cost and time -> faster and more frequent release of reference geo-information (e.g. European datasets) 28 August, 2013
