RESEARCH AND APPLICATION OF LIDAR TECHNOLOGY IN CADASTRAL SURVEYING AND MAPPING
The state attaches great importance to the issue of the right to the use of rural land. At present, China is carrying out a large-scale mapping and confirmation of rural house sites and rural houses. The traditional measurement method mainly adopts total station or RTK manual measurement method, which is characterized by high work intensity, complex operation procedure and labor-consuming. There are hundreds of thousands of villages in China. With the development of science and technology, it is an inevitable trend to use new technologies in rural cadastral surveys to improve their efficiency and quality. LiDAR scanning technology has the advantages of high efficiency, flexibility, reliability, and high accuracy, which meet the requirements of tasks and schedules that are difficult to complete with traditional measurement methods. This paper is based on the AS-300H multi-platform LiDAR system of Huace Navigation, which integrates UAV and vehicle LiDAR for cadastral surveying and mapping. It proves that LiDAR using in rural cadastral mapping has low labor intensity, high efficiency and accuracy. At the same time, the advantages and disadvantages of LiDAR technology for cadastral mapping are also summarized and elaborated, which has a good reference and significance for those who are currently conducting rural housing and cadastral mapping work.
