Expectations

• A lot of belief, but limited real good practices
• Statements
• Most important GI-development ever
• Exiting times
• Vital for poverty reduction in the world

22
Attention

• Conferences on SDI only, with increasing number
  of visitors.
• Issue on regular GI conferences
• Study days
• Attention in the written press, however
  scientific papers are limited.

23
Publications in geobase
24
Stakeholders involvement

• Strong support from the data-suppliers and
  Companies (Intergraph en ESRI grants)
• Users participation and awareness is limited
• Scientific research is also limited (change of GI
  research tradition)

25
Benefits

• Expected benefits are high
• Only projective studies (Netherlands, INSPIRE)
• No real impact evaluation (period is short)

26
Personal Reflection

• SDI is natural development from an historical
  perspective
• I am a strong believer in its potential,
• but more hard facts and figures are needed on
  successes, benefits/costs and users demand.
• scientific research

Spatial Data infrastructuesA small hype, but
it will hopefully become a hit!
