“…Most paddy field areas were submerged in water for over three days, preventing seedlings from growing. Based on the result, this study shows agreement with the other previous study which indicated that flood mostly occurs due to its terrain structure, where low-lying areas like paddy fields are located [50,54]. In general, it is challenging to perform flood classification using radar sensors when the land pixels have similar characteristics to water pixels.…”

“…The technology of GIS helps to organize data and understand their spatial relationship and provides a powerful means to analyze and synthesize the information about them. As they are examples of applications in environmental studies, they are reported in the recording of changes in forest areas (Collins and Woodcock 1996;Mas 1999), in the measurement of flooded areas (Alexandridis et al 1998), in forest fires and in deforestation (Kuntz and Karteris 1993), in the inventory of rangelands (Platis et al 2001), and in the changes of rangelands in the watershed of torrents over time (Ainalis et al 2006). The information systems have been designed to collect, store, and analyze objects and phenomena, in which geographic location is an important characteristic or is crucial for the analysis (Running et al 1994).…”

“…Την ίδια χρονιά παρουσιάζεται και η εργασία των Barrett and D'Souza (1990), όπου γίνεται µια ανασκόπηση των τεχνικών εκτίµησης της βροχόπτωσης µέσω εικόνων παθητικών συστηµάτων radar. Εικόνες παθητικών συστηµάτων radar χρησιµοποιήθηκαν επίσης για τη εκτίµηση της επιφανειακής εδαφικής υγρασίας (Owe et al, 2001), ενώ εικόνες από ενεργητικά συστήµατα radar χρησιµοποιήθηκαν για τη µέτρηση πληµµυρισµένων εκτάσεων στο Ν. Κιλκίς (Alexandridis et al, 1998) και για τη συσχέτιση της εδαφικής υγρασίας µε τη διακύµανση του σήµατος επιστροφής σε αγροτική περιοχή της Αγγλίας (Alexandridis, 1996). Οι εικόνες του δορυφόρου NOAA AVHRR έχουν επίσης χρησιµοποιηθεί για ένα πλήθος υδρολογικών εφαρµογών όπως για την οριοθέτηση αγρο-οικολογικών ζωνών (Verhoef et al, 1996), για τον υπολογισµό του ισοδύναµου νερού χιονοσκεπούς έκτασης (Xu et al, 1993, για τη µέτρηση της αρδευόµενης έκτασης µεγάλων συστηµάτων και την εποχιακή διακύµανση της επιφανειακής θερµοκρασίας θαλασσών (Marullo et al, 1999).…”
