激光雷达（Lidar）数据服务

激光雷达（Lidar）是指安装在飞机上的测距与机载激光探测系统，量测地面物体的三维坐标，从而生产Lidar点云数据。Lidar点云数据通过相关软件数据处理之后，就能够生成精度较高的数字地面模型DEM和等高线图。机载激光雷达系统在以下几方面的主要应用：测制地形图、环境检测和灾害调查、测绘海岸地区、林业项目和城市规划等。

LiDAR (Light Detection and Ranging) refers to an airborne laser ranging and detection system installed on aircraft, which measures the three-dimensional coordinates of ground objects to generate LiDAR point cloud data. After being processed with relevant software, LiDAR point cloud data can be used to produce high-precision Digital Elevation Models (DEM) and contour maps. Airborne LiDAR systems have major applications in the following aspects: topographic mapping, environmental monitoring and disaster investigation, coastal area surveying and mapping, forestry projects, and urban planning, among others.
