Drone-based glacier mapping of Nordenskiöldbreen and Tunabreen in Svalbard, 2024

This database contains drone-based mapping data of two glaciers, Svalbard, Norway. The glaciers are Tunabreen in Templefjord and Nordenskiöldbreen in Billefjord. The dataset was generated using a structure-from-motion (SfM) method using drone-based imagery. The data was processed with Agisoft Metashape and the processed data consists of digital elevation models (DEMs) in georeferenced .TIF file format, orthomosaic maps in georeferenced .TIF file format, and textured 3D models in .STL and .JPG file format. In addition, a process report in .PDF file format is included for each dataset. Mapping was conducted with a DJI Mavic 3 Pro Enterprise. The mapping area covers the crevassed glacier fronts. Data collection was conducted on Nordenskiöldbreen in Spring 2024 (2024-04-29) and Tunabreen in Summer 2024 (2024-09-04).

本数据库包含挪威斯瓦尔巴群岛两座冰川的无人机测绘数据，分别为坦普尔峡湾的腾纳布冰川（Tunabreen）与比勒峡湾的诺登斯基厄尔冰川（Nordenskiöldbreen）。本数据集基于无人机影像，通过运动恢复结构（Structure-from-Motion, SfM）方法生成，并使用Agisoft Metashape软件完成处理。处理后的数据包含地理配准的.TIF格式数字高程模型（Digital Elevation Model, DEM）、地理配准的.TIF格式正射影像图，以及.STL和.JPG格式的带纹理三维模型。此外，每份数据集均附带一份.PDF格式的后处理报告。本次测绘采用大疆（DJI）Mavic 3 Pro Enterprise无人机，测绘区域覆盖带有裂缝的冰川前缘。数据采集工作分别于2024年春季（2024-04-29）在诺登斯基厄尔冰川、2024年夏季（2024-09-04）在腾纳布冰川完成。
