Rural cadastral surveying and mapping based on the fusion of airborne LiDAR and high-resolution remote sensing images
Rural cadastral surveying and mapping is an important basis for rural land planning.There-fore,a rural cadastral surveying and mapping method based on the fusion of airborne light detection and ranging(LiDAR)and high-resolution remote sensing images is proposed in this paper.Firstly,airborne LiDAR mapping is done for rural cadastral data,airborne LiDAR point cloud data is collected and di-vided into blocks.Then,high-resolution remote sensing images of rural cadastral are segmented and fused with the registration of airborne LiDAR point clouds and remote sensing images to generate rural cadastral maps,and to complete rural cadastral mapping based on the fusion of airborne LiDAR and high-resolution remote sensing images.It is concluded from the experiments that the area error by the designed method does not exceed 1%,and the cosine similarity between the products of surveying and mapping and those of real measurements can meet the accuracy requirements,it can not ony precisely reflect the characteristics of rural cadastral shape,area,contour,etc.,but also provide accurate surveying and mapping products.
