典型长城无人机倾斜摄影数据集（榆林-嘉峪关）

针对明代土长城，选择了榆林到嘉峪关之间的几十处典型点长城，进行了低空无人机倾斜摄影真实场景三维建模，生成了高精度正射影像、DEM和三维模型，每处典型点大小长宽500m左右，地面空间分辨率1cm到5cm，可用于进行长城完整性评价和展示。

For the earthen Great Wall of the Ming Dynasty, dozens of typical sections between Yulin and Jiayuguan were selected. Low-altitude UAV oblique photography was employed to conduct real-scene 3D modeling, generating high-precision orthophotos, DEM, and 3D models. Each typical section measures approximately 500 meters in length and width, with a ground spatial resolution ranging from 1 cm to 5 cm, which can be used for integrity assessment and exhibition of the Great Wall.
