摘要
以江西省抚州市东乡县井山水库库区1∶2 000地类地形图测绘为例,系统阐述了利用无人机低空航测系统进行水利工程库区地类地形测绘的内、外业工作流程,制作了整个库区1∶2 000 DOM和数字线划图(DLG),并对DLG成果进行了精度评价。结果表明,成果质量满足相关规范的技术要求。
Taking 1∶2 000 topographic map surveying and mapping of Jingshan reservoir area which located in Dongxiang County Fuzhou City Jiangxi Province for example,we described the indoor and field work flows of terrain surveying and mapping using UAV aerophotogrammetry system in this paper.Then,we produced the 1∶2 000 digital orthoimage(DOM)and digital line graphic(DLG),and evaluated the precision of DLG.The results show that the DLG produced by UAV aerophotogrammetry technique can reach the precision needs of corresponding technical specifications.
