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。

This dataset targets the earthen Great Wall of the Ming Dynasty. Dozens of typical sections of the Great Wall between Yulin and Jiayuguan were selected as research sites. Low-altitude UAV oblique photography was employed to conduct 3D modeling of real-world scenes, and high-precision orthophotos, Digital Elevation Models (DEMs) and 3D models were generated. Each typical site covers an area of approximately 500m × 500m, with a Ground Sampling Distance (GSD) ranging from 1 cm to 5 cm. This dataset can be utilized for Great Wall integrity assessment and display.
