GREEN AREA AND VEGETATION COVER INDEXES OF THE SQUARES IN THE MUNICIPALITY OF ITABERAÍ, GO
Palavras-chave:
NDVI, Vegetation Cover, Index, Urban AreaResumo
The interest in analyzing green spaces in urban areas and correlating them with human health has
expanded due to rapid urbanization, increased pollution, and growing trends of physical inactivity among
the population. Considering the importance of preserving natural areas for promoting public health, the
present study aimed to evaluate green spaces (green areas, vegetation cover, and vegetation cover
percentage) in the Municipality of Itaberaí, Goiás. For this purpose, with the assistance of Geographic
Information Systems (GIS) technology, the Green Area Index (GAI), the Vegetation Coverage Index
(VCI), and the Vegetation Coverage Percentage (VCP) of the studied urban area were calculated. In
the analysis of the IAV, the base map from Google Satellite in the QGIS 3.28.10 software was used;
however, the ICV was measured using the Normalized Difference Vegetation Index (NDVI), calculated
from images downloaded from the CBERS-4A satellite. With the application of the methodology in
question, Itaberaí demonstrated that only 13.80% of its urban territory is covered by vegetation.
Regarding the IAV, the study obtained a value of 1.32 m2/inhabitant, classified as very poor by the
Brazilian Society of Urban Arborization (SBAU). Given the above, it is concluded that the urban area of
Itaberaí requires special attention regarding the analyzed topic, as the city does not meet the
internationally recommended levels of interurban vegetation.
