Abstract
With the development of national economic construction, the importance of terrain-level three-dimensional is more and more prominent, and high-precision Dem, DSM production has become an important task of local natural resources production. The cycle is also becoming shorter and shorter. In the process of data acquisition in mountainous and high mountain areas, it will be restricted by many factors such as terrain conditions, communication signals, vegetation coverage and so on, which will make the work more difficult. In order to solve this kind of problem, there are many kinds of new measuring technology emerging in recent years, among which lidar technology is the first one. Data acquisition of complex terrain by laser echo technology can effectively improve the accuracy of digital elevation model, greatly reduce the workload and shorten the execution time. In this paper, the technology of Airborne Lidar is applied to mountain terrain surveying and mapping, and the data of 1:10000 scale laser point cloud in high mountain area is obtained by using fixed-wing aircraft carrying Galaxy-T2000 airborne lidar, digital Elevation Model based on point cloud data, the results of the project have been widely used in resource exploration, urban planning, agricultural development, hydraulic engineering, land use, Environmental monitoring, transportation, earthquake prevention and disaster reduction, and the design of basic public facilities such as national key construction projects, serve as basic data for the overall planning of the survey area.
