Geoprocessing applied to the study of the urbanization process and its effects in Teresina, Piauí

Abstract

Dating back to the 18th century, the urbanization process has led to the development of the industrial sector in urban centers, resulting in an increase in the economy. On the other hand, this phenomenon has caused several environmental implications, such as the formation of heat islands and reduction of vegetation cover. Given this scenario, this paper aims to present a geospatial analysis of the urbanization process and some of its effects in Teresina over 30 years, making use of Geoprocessing and its tools. To this end, data from USGS, Mapbiomas, Google Earth Pro were obtained for the study of temperature variation, land cover and land use changes, urban expansion and statistical correlation, being possible to identify the increase of the urbanized area - and its temperature - in detriment of the subtraction of green areas.
