摘　　要：文章首先对无人机航空摄影测量技术进行介绍,然后对0.2 m分辨率的航空遥感影像资料与1.0 m分辨率的遥感影像资料生产的DOM在土地利用现状调查过程中的作用和效果进行了对比分析。利用无人机航空摄影测量技术获取项目区内优于0.2 m分辨率的影像并生成数字正射影像图,实现将高分辨率航空影像成果应用于第三次全国国土调查,相较于1.0 m分辨率的数字正射影像图,这在很大程度上提升了三调工作成果的精度和调查的准确度,减少了外业工作量,提高了第三次全国国土调查工作的效率。This article first introduces the application of UAV aerial photogrammetry technology,and then compares and analyzes the roles and effects of DOM produced by 0.2 m and 1.0 m resolution aerial remote sensing image data in the process of land use survey.The UAV aerial photogrammetry technology is used to obtain the images with better than 0.2 m resolution in the project area and make DOM,which realizes the application of high-resolution aerial image results in The Third National Land Survey.Compared with DOM of 1.0 m resolution,DOM of better than 0.2 m resolution has such advantages as improving the work accuracy and efficiency of The Third National Land Survey,and reducing the workload of field work.
