Photogrammetry Digital Elevation Model and Orthomosaic of Thores Glacier, Ellesmere Island, Canada

This dataset is used to quantify the detailed physical characteristics of Thores Glacier and its interaction with adjacent Thores Lake, including glacier extent, surface features, and surface elevation during a July 2019 field campaign. These measurements were limited to the lower part of the glacier (mainly ablation area) due to access limitations and snow cover higher up limiting the effectiveness of the photogrammetry survey. We took a series of pictures of Thores Glacier, Ellesmere Island, Canada in July, 2019 to build a three-dimensional model of the glacier. These photos show what the glacier looked like at that time including streams on the glacier surface.

本数据集用于量化2019年7月野外考察期间，托雷斯冰川（Thores Glacier）及其与邻近托雷斯湖（Thores Lake）相互作用的详细物理特征，涵盖冰川范围、地表特征与地表高程。由于通行限制以及冰川上部积雪影响摄影测量（photogrammetry）调查的有效性，本次测量仅覆盖冰川下部区域（主要为消融区）。2019年7月，研究团队于加拿大埃尔斯米尔岛（Ellesmere Island）拍摄了一系列托雷斯冰川的影像，用于构建该冰川的三维模型。这些影像完整记录了当时该冰川的样貌，包括冰川表面的径流。
