  1. Enabling Technology for Participatory Spatial Decision Making Hans Voss Gennady Andrienko Natalia Andrienko Spatial Decision Support Team http://www.ais.fhg.de/and/

  2. Participatory Spatial Decision Making Interactive, web-based GIS Multi-Criteria, spatial decision support tools • Collaboration support • Discussion fora • Argumentation structure • Shared documents • Voting Geocoding of discussion elements, linking map objects and arguments

  3. The Context Past: production of thematic maps and their analysis is a business of professional designers and cartographers • Wide spread availability of statistical graphics and GIS software • Appearance of visualization and mapping services in the Internet Now: Problem: • Thematic mapping and decision support tools become principally available to novice and casual users, but • Many potential users lack the required knowledge to utilize the tools

  4. Common Access to Geographically Referenced Data CommonGIS Approach CommonGIS Project and Software Provide intuitive tools and build semantics and smart user support into the software • www.commongis.de • Esprit Project No. 28983 • 10/1998-06/2001  Enable learning while doing

  5. Basic characteristics • Automated map design • Interactive maps for visual data exploration • Linked statistical graphics displays • Intelligent problem solving support … same interactivity in local application and on web client (Java applet)

  6. Interactive displays • Dot plot • Scatter-plot (matrix) • Parallel coordinates plot • Table lens view • Dynamic query device • Various classification tools … and • Various styles of interactive maps

  7. Multi-Criteria Decision Making

  8. The Wallis Example

  9. Scores and ranks of Options assigning weights to criteria aggregating values

  10. Comparison of results obtained with different preferences (weights)

  11. Sensitivity analysis

  12. Spatial Decision Support with CommonGIS Multiple Criteria A variety of highly interactive, integrated, computational and visual tools Cost/Benefit Criteria Priorities Ranking and Classification of options Manual editing of ranks Parallel Coordinate Plots Utility Bars Utility Wheels

  13. Cooperative Decision Support Various kinds of voting procedures Collection and analysis of votes Integration with web-based groupware tool Zeno Jankowski, P., Andrienko, N., and Andrienko, G.: Map-Centered Exploratory Approach to Multiple Criteria Spatial Decision Making, International Journal Geographical Information Science, 2001, V.15 (2), pp. 101-127
