IDENTIFICAÇÃO DE ÁREAS VERDES URBANAS A PARTIR DE IMAGENS DE SATÉLITE WORLDVIEW-II: O CASO DAS PRAÇAS NA CIDADE DE MONTES CLAROS – MG / IDENTIFICATION OF URBAN GREEN AREAS FROM SATELLITE IMAGES WORLDVIEW-II: THE CASE OF SQUARES IN THE CITY OF MONTES CLAROS - MG

Abstract

The existence of green areas within the urban area directly influences the improvement of environmental and social conditions. Based on this assumption, the discussions here aim to classify squares as green areas or public spaces, based on their presented functions, such as ecological function, esthetics, leisure and permeable area of 70%. Thus, with the main focus of the city of Montes Claros, the present work seeks to apply the concepts, methods and techniques that assist in the identification, classification, quantification and mapping of the city squares, defining them as green area or free space. The methodology used in the delimitation and classification of the squares was based on the literature review and the use of satellite images with high spatial resolution, as well as in the field work. It was observed that the squares considered as green areas are arranged in a heterogeneous way in the city, occupying from subdivisions with more precarious conditions to more dynamic and structured places, noting that there are still some places that do not have these areas.  It is concluded that the city of Montes Claros has about ninety-six squares, of these, eighty-one were classified as free spaces because they have part or none of the functions to be designated as green area and sixteen were considered as green areas because they presented all functions.
