The method used in the article is simulations to demonstrate how the analysis of the Viewsheds illustrates the transformations of the city over time, with urbanization and the alteration of sight fields and nodal points. We analyze Belo Horizonte city designed in 1897 and compared to the current city in terms of visibility. An analysis of viewsheds would show areas that are visible from points using computational tools. The problem addressed in this article is the lack of control, along the time, of viewshed – planning a city, which has resulted in the disorientation of people, expensive transportation, and the annulment of local identity. The hypothesis related to the problem are presented through a comparative analysis of the territorial occupation of the past and the present, generating a set of information that can contribute to future studies.
