Collaris is a website developed during a 36 hours Hackaton with the subject being “City security"
We create a website where people would be able to check the safest and most dangerous areas in their cities. Gathering crime data from external websites and twitter, Collaris show them as spots on the map. Crimes that happened between 1 day and 1 week, are shown as big dark red spots. The spots go until light yellow, that represents crimes between 3 months and a year.
After that, crimes do not appear on the map anymore. Users can use the timeline on the bottom of the screen to watch how crimes are evolving. If the city is getting better or the crimes are relocating between neighbourhoods.
