Métodos de cartografia e geoprocessamento aplicados na gestão de inconsistências de limites intermunicipais

estudo de caso entre Nova Lima e Belo Horizonte, MG

Abstract

Techniques of remote sensing, GIS and spatial data modeling are essential tools for planning in all levels of government. However, even with the widespread dissemination of these technologies in mapping activities, in Brazil, studies applied in the management of inconsistencies involving municipal boundaries are very scarce. Many municipal boundaries were described for the last time in the 1950s, using a colloquial language that describes the boundaries making references to natural landforms. Nowadays there are problems related to mischaracterization of these landforms by the action of urbanization, mining and other factors that severely alter the landscape. Furthermore, there are inconsistencies related to cartographic documents used as the basis for mapping the boundaries. The maps may have been generated in different types of Geodetic Systems, so if the map data is improperly processed or misinterpreted, distortions and incompatibilities are transferred to the resulting analysis. Changes in municipal boundaries cause economic and financial implications for municipalities, so it was also examined the economic issues involved in the study area in order to evaluate the possible losses arising from modification of bounds. Thus the study aims to identify factors that that cause difficulties to demarcation of boundaries between municipalities and propose a methodology for delimitation of boundaries focusing on the case study of border between Nova Lima and Belo Horizonte
