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). 00_ReadMe.txt 01_2024_Tunabreen_Images.zip - Contains all raw images. 01_2024_Nordenskiöldbreen_Images.zip- Contains all raw images. 02_2024_Tunabreen_DEM.tif - Contains the digital elevation model.02_2024_Nordenskiöldbreen_DEM.tif- Contains the digital elevation model.03_2024_Tunabreen_Ortho.tif - Contains the orthomosaic map.03_2024_Nordenskiöldbreen_Ortho.tif - Contains the orthomosaic map.04_2024_Tunabreen_Report.pdf - Contains the post-processing report. 04_2024_Nordenskiöldbreen_Report.pdf- Contains the post-processing report. 05_2024_Tunabreen_Model.stl - Contains the 3D model. 05_2024_Nordenskiöldbreen_Model.stl - Contains the 3D model. 06_2024_Tunabreen_Texture.jpg - Contains the 3D model texture. 06_2024_Nordenskiöldbreen_Texture.jpg - Contains the 3D model texture.本数据库包含挪威斯瓦尔巴群岛两处冰川的无人机测绘数据，分别为滕普尔峡湾（Templefjord）的图纳冰川（Tunabreen）以及比勒峡湾（Billefjord）的诺登舍尔德冰川（Nordenskiöldbreen）。 该数据集通过无人机影像结合运动恢复结构（structure-from-motion, SfM）方法生成，并采用Agisoft Metashape软件完成后期处理。处理后的数据包括地理参考的.TIF格式数字高程模型（digital elevation models, DEMs）、地理参考的.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格式的处理报告。 本次测绘采用DJI Mavic 3 Pro Enterprise无人机完成，测绘区域覆盖发育有冰裂缝的冰川前缘。数据采集时间分别为2024年春季的诺登舍尔德冰川（采集日期：2024-04-29）与2024年夏季的图纳冰川（采集日期：2024-09-04）。 数据集文件清单： 00_ReadMe.txt：说明文档 01_2024_Tunabreen_Images.zip：包含全部原始影像数据 01_2024_Nordenskiöldbreen_Images.zip：包含全部原始影像数据 02_2024_Tunabreen_DEM.tif：包含数字高程模型数据 02_2024_Nordenskiöldbreen_DEM.tif：包含数字高程模型数据 03_2024_Tunabreen_Ortho.tif：包含正射影像图数据 03_2024_Nordenskiöldbreen_Ortho.tif：包含正射影像图数据 04_2024_Tunabreen_Report.pdf：包含后期处理报告 04_2024_Nordenskiöldbreen_Report.pdf：包含后期处理报告 05_2024_Tunabreen_Model.stl：包含三维模型数据 05_2024_Nordenskiöldbreen_Model.stl：包含三维模型数据 06_2024_Tunabreen_Texture.jpg：包含三维模型纹理数据 06_2024_Nordenskiöldbreen_Texture.jpg：包含三维模型纹理数据
