Tree windbreaks have multifunctional benefits including wind damage reduction, soil erosion control, and biodiversity conservation. The removal and low adoption of tree windbreaks due to agricultural expansion are issues in many regions despite their critical role in improving agricultural sustainability. Farmers’ and landowners’ recognition of the benefits of windbreaks in their cultivation environments is necessary to preserve windbreaks. To visualize the benefits of windbreaks using remote sensing techniques, we focused on the top-to-bottom height of soil ridges, which are created homogeneously throughout the field using a machine. In this paper, we propose the use of soil ridge height as a remote sensing indicator to evaluate the spatial distribution of wind erosion. We tested two different remote sensing approaches at a potato field: one was an unmanned aerial vehicle (UAV) and the other was an Apple iPad Pro with a built-in light detection and ranging (LiDAR) sensor. Based on geographic information systems (GIS), the digital elevation model (DEM) was divided into grids with one ridge-furrow pair, with the ridge height given by the difference between the maximum and the minimum elevations in each grid element. The grid-based analysis of the differences in ridge heights between two periods was less affected by the positioning error than the DEM of difference. In a year with large erosion of up to 0.07 m, the spatial pattern of the wind erosion was identified from a single...
