Abstract

The objective of this study was to evaluate the use of satellite image bands to map agricultural areas in Petrolina-PE, utilizing time series and machine learning algorithms. The Random Forest (RF) and Temporal Convolutional Neural Network (TempCNN) models were compared in identifying land use and cover classes, with an emphasis on agricultural crops that are economically important to the region. Sentinel2 images were organized into data cubes, and samples were collected to train the classifiers and validate the maps. Both models performed well in distinguishing the classes, with RF excelling in some specific classes, while TempCNN achieved higher overall accuracy, demonstrating robustness for largescale mapping of agricultural areas.
