GIS projects 2012
Marc van Kreveld
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
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 3Meeting II: May 15Presentations 1: May 22
Meeting III: June 5Meeting IV (opt.): June 13/14Presentations 2: June 21???
Evaluation
• Based on meetings: initiative, progress, ideas
• Based on two hand-ins(May 25 and July 4)
• Based on two presentations
Topics1. Flow maps2. Label placement for islands3. Time-space maps4. Non-contiguous area cartograms5. Zoning, or political redistricting6. Touristy routes through nature7. Valleys and ridges in mountain areas8. Mountains and peaks9. Trajectory set visualization10. Spatial interpolation in an environment
1. Flow maps
2. Label placement for islands
3. Time-space maps
4. Non-contiguous area cartograms
5. Zoning, or political redistricting
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
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?
8. Mountains and peaks
From Wikipedia:• A mountain is a large landform that stretches
above the surrounding land in a limited area usually in the form of a peak. A mountain is generally steeper than a hill
• There is no universally accepted definition of a mountain. Elevation, volume, relief, steepness, spacing and continuity have been used as criteria for defining a mountain
9. Trajectory set visualization
10. Spatial interpolation in environments
• How do you define and compute spatial interpolation when it is influenced by land cover?
