Soil layer thickness detection in land rearrangement project by using GPR data

As an important indicator of the land quality of the land rearrangement project, soil layer thickness plays a vital role in cultivation and supporting crops growth. Hence, it is of great importance to accurately identify the soil thickness for overlay design, quality control/quality assurance. Currently, there is no standard and mature technology for soil layer detection. This paper proposes a novel method based on an accurate mode to discriminate soil layer boundary for soil layer thickness detection in GPR images. Comparing with traditional detection methods, the non-destructive technology is more rapid, efficient, and cost effective, and the performance of this new approach is greatly improved by using new image processing techniques. To illustrate the performance of the novel data processing technique we conducted a verification test on a land rearrangement area in Yanqing County, Beijing, China. Based on the soil layer thickness detection result, contour map of this area is generated automatically for quality detection and quality control guidance.
