2 Experiment Ron van Lammeren 2/24 Wageningen University

3 Perception oriented research figuur 7 aantal proefpersonen x 200 3D 1000 x D 2500 x D 2500 x D 1000 x D 200 x 200 2D 1 slecht goed the impact of 2D versus 3D, (1999) details / resolution layman versus peers distance, size, height Ron van Lammeren 3/24 Wageningen University

4 Expectations & Perspectives may stimulate collaboration. a metaphor for a planning and case study environment may provide support for dialogue essential to be able to communicate the complex environmental issues it supports formation of a joint perception and understanding may support coordinated activity may motivate, demonstrate, create and put into context for the domain of spatial planning and environmental studies Ron van Lammeren 4/24 Wageningen University

5 Fabritius viewer Ron van Lammeren 5/24 Wageningen University

6 Peep box Peep Box Components Shoe Box peep-hole scene pictures pellucid foils objects Ron van Lammeren 6/24 Wageningen University

7 Virtual Reality: peep box metaphor Components Viewer VR-scene Geo-referenced 3D-object Light 2D - geodata + elevation Background/ Panorama Ron van Lammeren 7/24 Wageningen University

8 2D geodata 3D visualisation? Level I (Current Archive) Level II (Space Shuttle) Level III (RTV) Level IV (RTV) Level V (RTV) 90 m spacing 30 m spacing 10 m spacing 3 m spacing 1 m spacing Ron van Lammeren 8/24 Wageningen University

9 Y Transform Geometrical structure Ron van Lammeren 9/24 Wageningen University

10 Geometrical and Graphical 3D-object construction 3D object geometry digital picture 3D object + = + = primitives bit plane Ron van Lammeren 10/24 Wageningen University

20 virtual worlds and avatars Ron van Lammeren 20/24 Wageningen University

21 Many conclusions I I I I Heim (1998) freedom of visualization via content, lay-out and perspective man-computer-man interaction 3D (!) scenes as research and design environment web enabled portable services new graphic and pictorial vocabulary 3D (!) visual interface for simulation models integration of simulation models process-control and users advisory by agent technology multi-user environments An outlook on parallel worlds Ron van Lammeren 21/24 Wageningen University

22 Our lessons - your interest match Catalyst in joint - cooperative research Catalyst in multi / inter / transdisciplinary research Division between geo data and geo visualization Geo-visualization refers also to interfaces Visualization of data Visualization in relation to tools [ to analyse, to simulate, to sketch] Geo-visualization as dialogue tool : Mental Mapped Researchers and Research population Amongst researchers Researchers and society (incl policy makers) Geo-visualization: doesn t the cure research illness Ron van Lammeren 22/24 Wageningen University
