本文以一个研究斯瓦尔巴群岛汹涌冰川的多学科项目为参考，探讨了摄影测量可以作为冰川学家研究工具的一些方法。所研究的两个冰川的摄影测量汇编是根据1990年的航空摄影制作的。在这个项目中，摄影测量主要被视为数字高程模型的来源，而不是作为制图工具。将摄影测量应用于北极地形时遇到的问题进行了考虑，并设计了一种方法，通过最大限度地利用可用数据来改善这些问题。介绍了摄影测量工作的成果，并分析了摄影测量数据精度量化的难点。讨论了将摄影测量衍生的数字数据用于冰川学分析和可视化的方法。
Using a multidisciplinary project studying surging glaciers in Svalbard as a reference, this paper examines some of the ways in which photogrammetry can be used as a research tool by glaciologists. Photogrammetric compilations of two of the glaciers under study were produced from 1990 aerial photography. Photogrammetry was regarded primarily as a source of digital elevation models in this project, rather than as a cartographic tool. Problems encountered in applying photogrammetry to the arctic terrain are considered and a methodology devised to ameliorate these problems by maximizing the available data is described. The results of the photogrammetric work are presented and difficulties in quantifying the accuracy of the photogrammetric data are examined. Examples of the ways in which the photogrammetrically derived digital data have been used for glaciological analysis and visualization are discussed.
