摘要
重点分析了机载LiDAR数据制作DEM的关键技术,并成功应用于黑龙江省2018年省级基础地理信息资源建设1∶10000地形图更新项目。建立了齐齐哈尔地区1∶10000 DEM模型,为经济建设发展以及洪涝易发区域提供了数据基础。
The key technologies of DEM production by airborne LiDAR data were analyzed,and they were successfully applied to the 1∶10000 topographic map update project of Heilongjiang provincial basic geographic information resources construction in 2018.A 1∶10000 DEM model was established in Qiqihar,which provided a data basis for economic development and flood-prone areas.
