1988年，国家地理学会出版了一幅新的珠峰地区1：50'000地形图。完整的地图内容来自1984年摄影测量飞行中获得的比例尺为1：35'000的航空图像。这幅广受赞誉的地形图采用瑞士摄影测量和制图技术制作而成，至今仍是重要的参考作品。我们将模拟数据（图像，轮廓）通过扫描转换为数字形式，并制作了纹理映射的3D计算机模型。该模型的DTM网格尺寸为10米，自然纹理像素尺寸为1米，是目前珠峰顶峰周围25 × 25公里区域的最佳数据集。本文简要介绍了该模型的制作过程，并讨论了与这种扩展的高分辨率真实感数据集的交互式实时可视化有关的一些问题。
In the year 1988 a new topographical map 1:50’000 of the Mount Everest region was published by the National Geographical Society. The full map content was derived from aerial images of scale 1:35’000, acquired in a 1984 photogrammetric flight. This highly acclaimed topographical map, produced with Swiss photogrammetric and cartographic know-how, serves until nowadays as an important work of reference. We took the analogue data (images, contours), converted them into digital form through scanning, and produced a texture-mapped 3D computer model. With a DTM of 10 m grid size and natural texture pixel size of 1 m this model is currently the best dataset available for an area of 25 by 25 km around the summit of Mount Everest. The basic data has been used for diverse scientific purposes and in a number of TV specials and Magazine reports.This paper reports briefly about the production procedure of the model and discusses some issues related to the interactive real-time visualization of such an extended high resolution photorealistic dataset.
