DGPS를 이용한 벼 수확량 지도 작성방법 = Yield Mapping Methods Paddy Field by using DGPS

다국어 초록 (Multilingual Abstract)

A yield monitoring system is useful and important in precision farming. Performance of an electronic yield monitor can be evaluated in controlled and field environments. A yield monitoring system and a DGPS were installed to a combine for yield mapping of a small sized paddy field, and yield mapping algorithms were investigated in this study. The yield variation in the field will be measured by yield flow sensor and grain moisture sensor at the end of the clean grain elevator. Yield map of the test field will be drawn in a point map and a linear interpolated map based on the results of the field test. The size of a unit yield grid in yield mapping is determined based on the combine traveling speed, effective harvesting width, and data storing period. The study shows the possibility of constructing the yield map of a small sized paddy field.
