AVALIAÇÃO ESPAÇO-TEMPORAL DA TRANSFORMAÇÃO DO USO DO SOLO E SEUS IMPACTOS NA TEMPERATURA DA SUPERFÍCIE POR SENSORIAMENTO REMOTO EM RIO VERDE-GO

Abstract

Motivated by the purpose of achieving economic success, humanity goes through numerous transitions in its geographical spaces, especially in cities, confirming that human relations with the environment are primarily marked by the of natural resources.extractions . In this sense, it is observed that the removal of vegetation cover and soil movement are tools used constantly to make viable the projects of society to improve the expansion of its cities. It turns out that anthropogenic actions, such as deforestation to open spaces, can negatively affect microclimatic parameters. Thus, the municipality of Rio Verde - GO, can be considered the embodiment of accentuated urbanization process, has become the object of study of this research. The objective of this study was to develop a condition based on an algorithm with the function of classifying the spatial distribution of land use in the urban perimeter of the Rio Verde municipality. And with this, we compare the urban sprawl data with the surface temperature variation (TS) of the study area. For this we used data extracted from orbital images collected by Landsat-5 / TM5 and Landsat-8 / OLI satellite sensors from 1985 to 2018 and provided by the United States Geological Survey (USGS). ), through the ESPA (EROS - Science Processing Architecture) platform. Through the study, the results presented one condition based on a hierarchical decision algorithm for land use classification, allowing to quantify the anthropized and green covered areas. In a second stage, the results also presented the thermal variability that occurred in Rio Verde during the study period.
