Interreg IIIB NWE funded project - Approx 4.7m eurosProposed 2003, began late 2005, and ran until June 2008Also funded by the UK - potential for its e-Planning programme

Objectivesshare technical competencies between NWE partners ...................3-dimensional visualisation, ICT applications to promote public consultation, environmental modelling, data collection & use for e-Planning in territorial development in NWE. a common architecture and methodology drawing on transnational experience and the knowledge of planning regulations and sustainability metrics in NWE, to enable citizens to view and respond to planned changes via home PCs.
refine and implement a test-bed system in a number of demonstrations in the NWE region, thereby increasing transnational experience. Evaluate and iteratively refine the methodology and the system architecture and applicable open standards.

Prototype toolswith which to evaluate:
Alternative approaches to showing planning proposals in internet based 3D contextsThe appropriateness of different forms of public participation tools (dialogue and commenting)If it is the right technology and approach for addressing these planning consultation issues. i.e.– Whether these tools may be easier to use for the same tasks than the
current approach?– The potential of such tools for enhancing effectiveness?
Interoperability

Citizens view & respond“usable, effective, efficient, engaging,
error tolerant, easy to learn”Acceptance vs simplicity
both EAEW & Groundwork staff getting a message across to the public prefer film to interaction so far!

‘takeaways’....more readily available data…
Auto-updated data, LiDARMore repetitive snapshotsReal-time reaction to presence & ambient intelligence
Conclusions

Low cost point clouds?

Espon Seminar April 2nd 2009 Luxembourg
major issues remain:usabilitylack of interoperability between the
emerging standardsavailability of data in these formats
a few years away from being sufficiently easy for access by all ?
