 	abstract = "The modeling and visualization of virtual cities is a point of interest in the research fields of simulations and computer graphics, also presenting contributions for the movies and games industries. Cities present complex population behaviors, with dense road networks and a huge number of buildings with varying architecture. In recent years, many methods based on geographical data and procedural techniques were presented, allowing the creation of content on a large scale. Still, there are known challenges to be explored in this field of research, including the lack of standards of communication and exchange of data between different levels in the hierarchy of a city. This work presents a framework for multi-level modeling of urban environments. At each stage of the framework?s pipeline, various elements and areas of a city are represented with increasing degrees of information. We modeled a real-world city based on geographical information following the presented framework, allowing its representation in different levels of abstraction and detail of data related to the population and environmental elements. We performed an analysis of social isolation data of the city, observing patterns in the population movement during the COVID-19 pandemic. Also, we modeled population routines based on the analyzed data, allowing the visualization of population groups and individuals in the environment.",
