浅析无人机航测在国土资源测绘中的应用

Analysis on the Application of UAV Aerial Survey in Land and Resources Surveying and Mapping

无人机航测是对传统航空摄影测量、摄影测量与遥感等测绘手段的有力补充,具有机动灵活、作业成本低、适用范围广、生产周期短等特点,在小区域和飞行困难地区高分辨率影像快速获取方面具有明显优势。无人机与航空摄影测量相结合使得“无人机数字低空遥感”成为航空遥感领域的一个崭新发展方向,在基础测绘、土地利用动态监测、智慧城市建设等方面具有广阔前景。相比传统测量,无人机航测作业成本更低、效率更高、时效性更强,深受测绘行业的欢迎,在国土资源测绘中应用也越来越广泛。

UAV aerial survey is a powerful supplement to traditional aerial photogrammetry,photogrammetry,remote sensing and other surveying and mapping methods.It has the characteristics of flexible maneuverability,low operating cost,wide application range and short production cycle and it has obvious advantages in fast acquisition of high-resolution images in small areas and difficult-to-flight areas.The combination of drones and aerial photogrammetry makes"UAV digital low-altitude remote sensing"become a new development direction in the field of aerial remote sensing,which has broad prospects in basic surveying and mapping,land use dynamic monitoring and smart city construction.Compared with traditional surveys,UAV aerial survey is more economic,more efficient and more time-sensitive,so it is well received by the surveying and mapping industry and is increasingly used in land and resources surveying and mapping.
