A cartografia de síntese e as estruturas verticais e horizontais da paisagem em ambientes urbanos suscetíveis à inundação

This article presents the methodological proposal for Synthesis Cartography, considering the dimensions (x, y, z, t) and the vertical (taxonomic scales) and horizontal (components and geographical attributes) dimensions for the spatial representation of the urban landscape dynamics, as well as the spatialization of flood susceptibles areas from two graphic scenarios (years 1989 and 2020), as support to municipal public policies. The study adopts the Census Sector Colonia do Marcal, located in the municipality of Sao Joao del-Rei, state of Minas Gerais, Brazil as a spatial clipping.The theoretical-methodological foundation was based on research with Multicriteria Decision Analysis for the application of modeling of areas susceptible to floods and inundations. The procedures consisted of preparing thematic algebra maps and elaboration of the graphic scenario of the Synthesis Cartography, considering the environment vertical and horizontal structures in the urban landscape. The two time-space models present areas of very high susceptibility in some common places, despite the expansion of the urban area, two large rivers plains did not alter the scenarios, even with the expansion of the amount of urban constructions. It is observed that, around other smaller fluvial channels, the classes high and very high susceptibilities to floods are because of the natural dynamics of flooding. The graphical scenario of the synthesis shows the influence of the energy, matter and information dynamics (EMI) flows of the area on the landscape environmental state, observed by vertical and horizontal structures.
