Presentation Transcript

  1. GIS projects 2010 Marc van Kreveld

  2. Two phases • Problem analysis (phase 1  report 1) • Literature study, reverse engineering • Statement of criteria • Dependency of criteria • Quantification of the criteria • Algorithm design (phase 2  report 2) • Specification of input and output • Algorithmic problem statement • Algorithm development • Efficiency analysis

  3. Three meetings • Prepare the meetings; think about it extensively first • Take the notes and figures of the ideas you had until the meeting Meeting I: May 6/7 Meeting II: May 19 Presentations 1: June 1 Meeting III: June 8/9 Meeting IV (opt.): June 23/24 Presentations 2: June 29

  4. Evaluation • Based on meetings: initiative, progress, ideas • Based on two hand-ins(June 4 and July 2) • Based on presentations

  5. Topics • Flow maps • Label placement for islands • Time-space maps • Non-contiguous area cartograms • Zoning, or political redistricting • Relative positions of regions • Touristy routes through nature • Valleys and ridges in mountain areas

  6. 1. Flow maps

  7. 2. Label placement for islands

  8. 3. Time-space maps

  9. 4. Zoning, or political redistricting

  10. 5. Relative positions of regions Is Norway closer to Sweden than to Finland? Should Austria be called South of Germany, East of Germany, or both? Degree of closeness, south-ness?

  11. 6. Touristical routes through nature • Assume: new national park needs road across • Passes by small natural sights • Has good views of large natural sights • Connects two or three points on boundary of park reasonably

  12. 7. Valleys and ridges • Linear features in mountain landscapes: ridges high and valleys low • Some valleys are more prominent than others (same for ridges) • Only prominent ones would be shown on small-scale maps • How to define and compute prominence?
