Atualização da base cartográfica em assentamentos informais

Abstract

Land owning is one of the main goals of human being. An expressive ammount of brazilians population lives in informal settlements, in wich the Favelas highlights as a recurrent urbanistc typology. Legal and urbanistic regularization of this kind of occupation, stablishes na improvement to economic patterns of the resident population. In Brazil, to promote the titration of this occupied space represents a challenge that goes further urbanistic techniques. It is also necessary to confront solid social concepts and a whole legal and registry bureaucracy. Belo Horizonte City Hall, through the Urban and Habitational Development Company URBEL, promotes on Special Zones of Social Interest characterized by vilas, favelas and Social Interest Housing Complexes construction works and other urban-developer actions, in order to enable them to constitute the Formal Urban Fabric. At the end of this process, the Land Regularization Program, guided by urban, legal, environmental and social standards recommended by the Municipal Housing Policy, allows the formal titration of the lands involved. Despite the existence of a Data Base containing all the informations generated from the technical activities developed in this process, those actions are not associated to a Geographic Information System (SIG). To obtain vector cartographic base in Favelas, elucidating the local land network, is fundamental to regularization processes. A brief study points the limit on the use of aerophotogrammetric restituition to this finality and indicates conventional topography as the right metodology.
