  3. Current Situation • IT was introduced in cadastre about 30 years ago • Geodetic Calculation programs > 1960 • Textual records > 1970 • Mapping systems > 1990 IT Renewal Strategy Europe

  4. Where is the problem ? • Individual developments • No standards • Fragmented software solutions • Maintenance difficult • Systems are too costly IT Renewal Strategy Europe

  5. New technical requirements IT Renewal Strategy Europe

  6. Need for renewal • Integration of register and maps for a better work flow • ISO and OGC standards • New business strategies in the organisations • Cadastre is a basic element of NSDI • Internet, e-land administration IT Renewal Strategy Europe

  7. General strategies • Step by step • big bang • re-engineering within the existing infrastructure • conversion of existing mainframe solutions into a client-server architecture IT Renewal Strategy Europe

  8. Step by step in the Netherlands • General information • Roman and French system • Notary Public plays important role • Land registers and cadastre in the hand of Kadaster • 1,000,000 transactions per year • cadastral registers and maps different systems, parts more than 20 years old • maintenance costs = 6 * modern systems IT Renewal Strategy Europe

  9. Step by step in the Netherlands • Renewal strategy was developed over 6 years = road map • find a balance between user demands for new functionality, availability and continuity and the demands on cost management and manageability IT Renewal Strategy Europe

  10. Step by step in the Netherlands IT Renewal Strategy Europe

  11. Step by step in the Netherlands • Renewal of the core system • new system built up in parts in a new environment while the old system is still running • 10 years synchronising both systems • periodical evaluation of the process IT Renewal Strategy Europe

  13. Big bang in Finland • Development of JAKO started in early 90s • integration of separated systems • design carried out until 1995 • implementation 1998 • JAKO as part of LIS • LIS is part of NSDI IT Renewal Strategy Europe

  14. Big bang in Finland • Functional improvement of data base maintenance • one seamless VMDS • improvement of information service • in operation since 5 years IT Renewal Strategy Europe

  19. Recommendations • Step by step approach • Complex and time consuming • Parallel data maintenance for long time • Customers have time to convert their systems • Employees‘ skills can be developed and experiences may influence new components IT Renewal Strategy Europe

  20. Recommendations • Big bang approach • Easier to implement • Long development and test phase • Short migration period • Customers have to be involved • Education program parallel to normal work process • New work flow needs new skills IT Renewal Strategy Europe

  21. Conclusion • Strategy has to fit in the situation in each individual country • All strategies have strengths and weaknesses • No cookbook, just good practice guidelines www.oicrf.org search under ‚IT renewal Enschede‘ IT Renewal Strategy Europe
