Abstract For rice growing areas in the tropics, experience shows that SAR Satellite sensor can provide the desired information due to acquiring images independently of cloud coverage or daylight conditions. The current study testifies the potential of SARdata for rice mapping. This paper discusses the methodology and result of using SARdata and GISin updating rice map for the local government in Zengcheng County of Guangzhou province, South of China. The methodology was carefully laid out and was determined to be easily implemented on a semi-automatic basis to facilitate frequent updating of rice map.
