چکیده مقاله:
Agriculture is a very important sector in the life of human beings as it provides food, bio-based energy, and fiber products. Remote sensing and other geospatial technologies have helped to study agricultural activities comprehensively. This research aimed to mapping of agricultural lands and assess their changes in Al-Hillah, Babylon province, Iraq during ۲۰۰۰-۲۰۲۱. The main datasets used for this research were Landsat TM, ETM, and OLI images. The classification models were based on Random Forest (RF), K Nearest Neighbor (KNN), Artificial Neural Network (ANN), and Support Vector Machine (SVM). These models were optimized using the random search optimization algorithm. The accuracy of the models was assessed using Overall Accuracy (OA), F۱-socre, and Kappa index. The results indicated that KNN is the best classification as it performed better than the three models. KNN achieved an OA of ۰.۹۵۴, ۰.۹۵۶, and ۰.۹۶۶ for the image data ۲۰۰۰, ۲۰۰۸, and ۲۰۲۱, respectively. Optimizing models’ hyperparameters yielded better classification accuracies in many occasions except SVM for the image data ۲۰۰۰ and KNN for the image data ۲۰۲۱. The assessment of spatial distribution of urban and agricultural lands showed that urban area growth was centric outwards from the city center and the latter expanded to encompass the surrounding areas from ۲۰۰۰ to ۲۰۲۱.
