Identification of paddy fields in Northern Japan using RapidEye images

Agriculture fields located in northern part of Japan having vector polygons as paddy, non-paddy and uncultivated attributes were investigated to identify paddy fields using RapidEye satellite images acquired on June 27 and July 28 of 2012. Paddy, other crop and uncultivated fields were selected from the vector polygons and the polygons were extracted from the images. A bimodal histograms of the extracted polygons were created and established identification algorithm for paddy field classification. The algorithm was applied to RapidEye image and created a map for active paddy fields of the area for 2012.
