Avaliação da dinâmica temporal da cobertura e uso das terras do município de Patos - PB utilizando MapBiomas©.

Abstract

Given the repetitiveness with which satellite images are acquired, it is possible to recognize changes in the landscape of a region in a given period of time by analyzing the extent and type of changes in use. The objective was to statistically evaluate, through descriptive analysis and regression, temporal data on the coverage and use of land in the municipality of Patos-PB obtained by MapBiomas© using a series of 36 years between 1985 and 2020. The statistical treatment was directed to the application of the analyzes of the data using the XLSTAT© Trial. The use of the MapBiomas web application as a tool to analyze the use and land cover provided satisfactory results quickly and accurately. It was observed that there were significant changes in area in the Non-Forest and Agricultural Natural Formation classes, where the greatest deviations occurred. The distribution was not symmetrical, kurtosis indicated a platykurtic distribution, where the greatest variations in amplitude and irregular distribution were in the Non-Forest and Agricultural Natural Formation classes. It could be said that there is agreement between the tests used in this work and the accuracy analysis performed on the images by Mapbiomas©.
