Visualização de informações em cidades participativas e suas interações

Abstract

Participatory cities are those that citizens participate in the construction and improvement of their common daily life. In this direction, the idea of this work is that through a website people can record issues/occurrences related to their city. Examples of occurrences are crimes, accidents, maintenance issues, among others. Through the same site, citizens can get global information about the city, resulted from the integration of the supplied data by the use of a visualization scheme. The goal of this work is to create views and interactions about the occurrences registered in a participatory city. For this, many concepts are studied like: data visualizing, Voronoi diagrams, quaternary tree, convex hull and Google Maps API. Starting from this studies, there is created a model visualization of occurrences. The resulting visualizations generate regions according occurrences densities. Based on occurrences densities and also in agreement with a context distribution the interaction between two classes of events befall. Criminal occurrences and police occurrences are the classes of events selected to interact. The wealth context distribution is apllied with the aim to be attractive for the criminal occurrences. The system behavior arising from interactions is analyzed and graphically represented.
