  1. Quality Management of Spatial Data Infrastructure – a Necessity for Investments Anders Östman & Jan Zakariasson Swedesurvey AB II Annual Conference of the CIS and Baltic Countries - Moscow Sept 2011

  2. Swedesurvey AB • An International Consultant company, owned by the Swedish Government • Provides services worldwide within Land Governance, NSDI and Human Resource Development • Acts as the Overseas Agency of Lantmäteriet, the Swedish mapping, cadastre and registry authority II Annual Conference of the CIS and Baltic Countries - Moscow Sept 2011

  3. NSDI version 1.0 Based on INSPIRE Legislation: Most EU countries have implemented the INSPIRE directive in their national legislations Business models: Mainly G2G (Goverment-to-government) Network services: Up and running, more or less Geoportal: A large number exists Data provision: Currently the main focus II Annual Conference of the CIS and Baltic Countries - Moscow Sept 2011

  4. NSDI version 2.0 Increase value to the user Increase involvement of private business and citizens NSDI monitoring at macro level (INSPIRE reporting, Balanced scorecard, SDI readiness index, SDI maturity index, ...) NSDI monitoring at micro level (service quality, data quality, investment analysis, ...) II Annual Conference of the CIS and Baltic Countries - Moscow Sept 2011

  5. Some statements about quality “The characteristics of a product or service that bear on its ability to satisfy stated or implied needs ” (American society for quality) “There is always another method for making a product cheaper and better” (Kaizen concept) Quality assurance of geospatial data production is mainly seen as a cost (Eurogeographics) Investment decisions requires proper quality management (Self-evident) II Annual Conference of the CIS and Baltic Countries - Moscow Sept 2011

  6. Readability Esthetic Basic measurements (distance, direction, area) Well established QA routines for production of paper maps Cartographic quality II Annual Conference of the CIS and Baltic Countries - Moscow Sept 2011

  7. Geospatial data quality Data quality elements Accuracy Completeness Consistency Currentness Producer oriented II Annual Conference of the CIS and Baltic Countries - Moscow Sept 2011

  8. Data Providers Subcontractors Crowdsourcing Data migration Data harmonisation (INSPIRE, Mash-ups) Providers of network services Availability, Response time, Number of concurrent users Providers of web applications Fast Correct and relevant information Flexible, customizable to the needs Low cost Convenient Reliable Quality challenges for SDI actors II Annual Conference of the CIS and Baltic Countries - Moscow Sept 2011

  9. Case Study 1 – Migration and harmonisation to INSPIRE INSPIRE schema NLS schema NLS database Data extraction Schema matching and mapping NLS shapefiles Source consistency test Shape to GML conversion Transformation rules Source GML files Schema transformation Schema transformation report Source data consistency report Schema matching & mapping report Target GML files II Annual Conference of the CIS and Baltic Countries - Moscow Sept 2011

  14. Quality in short • The quality of data and services are essential key issues for further development of (investment in) a NSDI • Data quality • New business models and data processing streams requires new quality assurance routines • Design of QA routines extremely important (risk minimization, parameters, acceptance thresholds) • Service quality • INSPIRE network services – ESDIN test suite • Web applications – Usability tests required II Annual Conference of the CIS and Baltic Countries - Moscow Sept 2011

  15. The role of Swedesurvey • Partnership with local and international expertise • Solving short term issues (implementation, development etc) • Strategic guidance • Capacity building II Annual Conference of the CIS and Baltic Countries - Moscow Sept 2011

  17. Conclusions NSDI version 1.0 based on INSPIRE A strategy for NSDI v 2.0 need to adress the private sector and citizens Quality of services and data are essential parts of such a strategy We have for several years worked on SDI, regional development and business development – experiences we wish to share with you II Annual Conference of the CIS and the Baltic Countries - Moscow Sept 2011
