Cartografia geomorfológica comparada: aplicações no município de Juiz de Fora (MG) como subsídio ao planejamento

Abstract

The production of geomorphological maps, in consonance with the morphostructural and morpho-sculptural aspects, leads to effective studies on the integration of the landscape, directing the use of these maps in related studies, such as in those about regionalization and on issues concerning environmental planning in urban settlements. Effectively, genetic, morphometric, morphographic and chronological expressions are attributed to the geomorphological map, as well as the dynamics of the processes resulting from the climatic performance over time. Due to the complexity of information the geomorphological survey covers, its cartographic registry still finds obstacles to a standardization of procedures or symbologies in the production script of the final geomorphological chart. Thus, the present work grants the approach of geomorphological cartography applied to the municipality of Juiz de Fora, broadening the debate on methodologies and techniques. The relief of the mentioned municipality belongs to the domains of the “sea of hills” (chain of hills), on Zona da Mata region. Based on this perspective, a geomorphological chart was produced, as well as the comparison of this document with an existing map of morphology for the municipality. Applied research has been also carried out, in order to collect information about the local geomorphologic system. The geomorphological chart that has been produced, based on the methods and techniques of relief cartography, was carried out with adaptations and resulted in an iconographic communicative document of the symbology. The formatting of the legend component has been assisted by graphic resources using the Geographic Information System (Sistema de informação Geográfica - SIG). Hence, the efforts related to the elaboration of this type of chart contribute to the discussions regarding the methodological procedures for the production of this document and emphasize the application of the methods developed in this work for the recognition of geomorphological systems of other landscapes in tropical domains.
