The low altitude data acquisition technology by unmanned aerial vehicle and aeroboat played important role in urban spatial information acquisition and updating. 无人机、飞艇等低空获取技术在城市空间信息的获取和更新方面发挥了积极的作用。
The system use of unmanned aerial vehicle platforms as a low altitude remote sensing and photogrammetry known as UAV low altitude remote sensing system ( UAVRS ). 采用无人飞行器作为遥感平台进行低空监测和摄影测量的系统称为无人飞行器低空遥感系统(UAVLowAltitudeRemoteSystem,简称UAVRS系统)。
