Utilização de técnicas de sensoriamento remoto na evolução do uso do solo no litoral sul de Pernambuco

Abstract

The objective of this research was to evaluate the use and occupation of the soil in the southern coast of Pernambuco from 2006 to 2017 and to estimate the Foliar Area Index as a means of corroborating data from the manipulation of information from the LANDSAT 5 and LANDSAT 8 satellites The research was developed in the Geoprocessing and Remote Sensing Laboratory (GEOSERE) located at the Federal Rural University of Pernambuco (UFRPE). It was used images of satellites with the lowest cloud coverage index possible. The scenes were imported into the Georeferenced Information Processing System (SPRING). The supervised classification was performed for each scene, where areas corresponding to the thematic classes were identified from the scenes obtained in the satellite images. Then, the leaf area index (LAI). As a result, it was found that the largest occupation belt on the south coast of Pernambuco is directed towards urban centers, both for the LANDSAT 5 scene and LANDSAT 8, where the expansion of this class was perceptible. IAF rates were low for both dates of the imagery used, although the 2017 scene was more extensive compared to 2006. Combining the results of the supervised classification with the IAF, Native Vegetation expressed the highest average for the IAF in 2006, but in 2017 suffered reduction, being surpassed by the agriculture class. IAF averages, together with their fall between the years 2006 and 2017, show that there is low vegetation cover on the southern coast of Pernambuco.
