Mensuração de índices de área verde através de imagem orbital de alta resolução: estudo de caso para o bairro São Francisco de Assis, Dois Vizinhos - PR

Abstract

The amount of urban vegetation indices reflects on beneficial to society at around, increasing the quality of life for residents of urban centers and generating benefits from air purification to protect against landslides. These indexes of urban green areas can quantify the trees present in a district or county and relate them to their size and the number of inhabitants, but it is necessary to quantify these areas by measuring the canopy of all trees. The present study refers to the quantification of green areas in the district São Francisco de Assis, Dois Vizinhos – PR, determining the distribution of the same, as well as indices for representing. In this perspective, will be working with an orbital high-resolution picture quickibird, high spatial resolution georeferenced and orthorectified, with control points collected in the field using GPS receivers geodetic and topographical to measure these areas in question. Green areas will be evaluated quantitatively through the area of the treetops measured by image processing softwares as well as qualitatively evaluating their distribution and differentiating classes of trees in urban forestry, representing this information using maps.
