雷达点云数据在省级地理信息资源建设中的应用

开展省级基础地理信息资源获取与更新,可有效解决区域地形图过于陈旧等问题,为基础设施建设、重大工程实施、防灾减灾提供保障,为国土空间规划、自然生态保护与修复、自然资源资产用途管控等生态文明建设主要任务提供权威、客观、精准、动态、可视化的基础地理信息数据支撑。机载激光雷达技术已广泛应用于省级基础地理信息资源获取与更新中,本文将从机载激光雷达数据获取、处理、成果输出等方面展开论述。

Application of LiDAR Point Cloud Data in Construction of Provincial Geographic Information Resources

The acquisition and update of provincial-level basic geographic information resources can effectively solve the problem that the regional topographic maps are too old,and provide guarantees for infrastructure construction,major project implementation,disaster prevention and mitigation,for national land planning,natural ecological protection and restoration,and natural resources.The main tasks of ecological civilization construction such as asset use control and control provide authoritative,objective,accurate,dynamic and visual basic geographic information data support.Airborne Li DAR technology has been widely used in the acquisition and update of provincial basic geographic information resources.It will be discussed from the aspects of airborne Li DAR data acquisition,processing and output.
