摘　　要：在南极利用高空间分辨率遥感影像进行数字地形图生产具有航空摄影测量、全野外数字测图等方法不具备的大范围、短周期和低成本等优势。本文以南极恩克斯堡岛、北山麓和Priestley冰川、Nansen冰架交汇区域为实验区,采用World View-3立体影像进行南极1∶5000数字地形图生产实验,形成了一套生产技术流程方案,并对生产技术流程方案进行精度检测,验证了该技术流程在南极1∶5000数字地形图生产的可行性。最后对利用World View-3立体影像进行南极1∶5000比例尺地形图产品生产存在的问题以及解决方法进行了简要论述,为后续南极大范围1∶5000数字地形图生产提供参考。Using high spatial resolution remote sensing images to produce digital topographic maps in Antarctica has the advantages of large-scale,short period and low cost that aerial photogrammetry and field digital mapping do not have.In this paper,taking the Ant-arctica Inexpressible Island,the Northern Foothills,the intersection area of Priestley glacier and Nansen ice shelf as the experimental area,the production experiment of Antarctica 1∶5000 digital topographic map is carried out by using the Worldview-3 stereo images,and a set of production technology flow scheme is formed.The accuracy of the production technology flow scheme is tested to verify the feasibility of the technology flow in the production of Antarctica 1∶5000 digital topographic map.Finally,the problems and solutions in the production of Antarctic 1∶5000 scale topographic map products using Worldview-3 stereo images are briefly discussed,which provides a reference for the follow-up production of Antarctic 1∶5000 digital topographic map.
