Drone-based glacier mapping of Fridtjovbreen, Vallakrabreen, Paulabreen, and Scheelebreen

This database contains drone-based mapping data of four glaciers in Svalbard, Norway. Fridtjovbreen on the west coast and Vallakrabreen, Paulabreen, and Scheelebreen which are three surging glaciers in Rindersbukta. 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, .JPG, and .PNG file format, and textured 3D models in .STL and .JPG file format. In addition, a process report in archived .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 during Spring 2025 (29.03.2025-02.04.2025). For Fridtjovbreen, two different models are available, one high resolution and one baseline resolution. The datasets for Paulabreen and Scheelebreen are combined.

本数据库收录挪威斯瓦尔巴群岛四座冰川的无人机测绘数据，分别为西海岸的弗里德约夫冰川（Fridtjovbreen），以及位于林德斯湾（Rindersbukta）的三座跃动冰川：瓦拉克拉布雷恩冰川（Vallakrabreen）、保拉冰川（Paulabreen）与席勒冰川（Scheelebreen）。本数据集基于无人机影像，采用运动恢复结构（Structure-from-Motion, SfM）方法生成，数据处理使用Agisoft Metashape软件完成。处理后的数据包含三类成果：地理参考格式的.TIF文件数字高程模型（Digital Elevation Model, DEM）；地理参考格式的.TIF、.JPG及.PNG文件正射影像图；以及.STL与.JPG格式的带纹理三维模型。此外，每份数据集均附带归档为.PDF格式的处理报告。本次测绘作业采用大疆（DJI）御3 Pro行业版（Mavic 3 Pro Enterprise）无人机执行，测绘区域覆盖带有冰裂缝的冰川前缘地带。数据采集工作于2025年春季开展，具体时段为2025年3月29日至2025年4月2日。针对弗里德约夫冰川，提供两种分辨率的模型：高分辨率模型与基准分辨率模型。保拉冰川与席勒冰川的数据集已合并。
