• History
• Projectdescription
• Application
• Field Reports
• Outlook
• Map Your World Project since 2009– Problem: complex (infrastructure, time-wise)
• Strategic Initiative FHNW, School of TeacherEducation:Promote the interest of secondary school students in technical professions
• Limitation: 4 lessons!
• Students record their daily routes (~ 1 Week)
• GPS data is uploaded, stored and processedin a central database (PostgreSQL)
• Web application provides results as maps showing spatial-kinesthetic behavior and motion patterns:
– Heatmap of GPS tracks
– Hotspots
– Indoorlocations
• Objective
– Introduce map and navigation technologies(GPS, map navigation and interpretation etc.)
– Create an awareness of Privacy and how Privacy is related to spatial data
• Privacy Policy
– Project requires credentials;
– Data is deleted after 1 month
– Project-name…
• Functionality Web application
– Computation of heatmap / hotspots etc.
– Filter options (time of day, day, age, sex)
– Movie / Animation of tracks (5‘ Interval)
• Requirements:
– Hardware: GPS Logger or Smartphone etc.
– Software: just a standard Webbrowser (FF,GC)
• First Week: 2 Lessons

Students comments:• “Which café in town did the most boys or girls go to? How long
did they stay there? What day of the week was it?”
• „On Sunday afternoon, Carlo did a bike tour in the forest. You know this because there’s a red point in front of Carlo’s house and the route he took in that time is too far to jog or walk.”

• “You could figure out where to place a kebab stand.”
• etc.
• Spread information…
• Find out about relations based on GPS tracks
• Optimise GPS-Track‘s Geometries
• Evaluation of other areas of application(urban planning, bike couriers, etc.)
• Projects ahead:
– Request of Prof. Dr. J.P. Mund (Forestry)
– August 2012 Lucerne (2 Classes)
– Schaffhausen (Q3/2012)
