The objective of this research is to support a design for grass-land amelioration. The design method with a spatial filter was developed in this research analyzing grass-land amelioration by the skilled engineer. The tractor installed a RTK-GPS and an IMU which acquired topographical features before and after field improvement, and the amplitude change under the spatial frequency domain was analyzed. As the result, the amplitude at the frequency of 0.04 [m−1] (wavelength 25m) was reduced dramatically by the improvement. A spatial filter was made to mainly eliminate frequency of 0.04 [m−1]. Applying the designed filter, the land before amelioration became moderately flat surface, that was similar to the land after amelioration. Moreover, there was a high correlation between cut and fill depth of actual ameliorated land and the filtered land. This result suggests that the developed system can be applied to the construction plan of grass-land.
