Resumo
The wide range of freely available satellite images and advances in computational methods have promoted the use of remote sensing techniques to analyze the Earth’s surface, improving analysis of vegetation. In regions such as the semi-arid zone of the Caatinga biome, this has been essential to assess the conditions and seasonality characteristic of
the local vegetation. The objective of this study was to generate land use and land cover classifications and assess changes between 2018 and 2020 through two approaches:
(1) classification of satellite image time series and (2) classification of each satellite image individually. This study concludes that the first approach using the Randon Forest method and NDVI time series enhanced the differentiation of land use and land cover classes in Petrolina-PE. View Full-Text
