Ogólnokrajowa mapa pokrycia terenu w Iranie została wygenerowana przez przetworzenie zdjęć z satelity Sentinel na platformie Google Earth Engine Cloud. W tym celu przetworzono ponad 2500 zdjęć z satelity Sentinel-1 i ponad 11 000 zdjęć z satelity Sentinel-2, aby utworzyć jeden zbiór danych mozaikowych za rok 2017. Następnie na podstawie dużej liczby próbek referencyjnych dla 13 klas wytrenowano metodę klasyfikacji opartą na obiektach Random Forest, aby wygenerować mapę pokrycia terenu w Iranie.
