| 摘 要： | 利用高分辨率立体测绘卫星遥感影像进行地貌更新，因其覆盖面积大、更新周期短等优势，在中小比例尺地貌要素更新中具有极大的应用潜力。本文分别利用WorldView-2和资源三号卫星影像，探索基于高分辨率立体测绘卫星影像的中小比例尺地貌更新技术方案流程，并在不同的试验区开展试验验证。试验结果表明：本文方法能够满足1：50 000比例尺地形图地貌更新精度要求，更新效率提升了约25%。

| Abstract: | Geomorphologic updating by using high-resolution stereo mapping satellite remote sensing image has great application potential in medium and small-scale geomorphic features updating because of its advantages of large coverage area and short updating period. In this paper, WorldView-2 and ZY-3 satellite images are respectively used to explore the technological process of small and medium scale geomorphic renewal based on high-resolution stereo mapping satellite images, and the experimental verification is carried out in different experimental areas. The results show that the proposed technical scheme can meet the accuracy requirements of 1:50 000 topographic map updating, and the updating efficiency is improved by about 25%. |
