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

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, ...)

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)

Cartographic quality
• Readability• Esthetic• Basic
measurements (distance, direction, area)
• Well established QA routines for production of paper maps

Geospatial data quality
Data quality elements• Accuracy• Completeness• Consistency• Currentness
Producer oriented

Quality challenges for SDI actors
• 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

• 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
Quality in short

• Partnership with local and international expertise• Solving short term issues (implementation,
development etc)• Strategic guidance• Capacity building

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
