Drone-based mapping of Gruvefjellet in Spring and Summer for cornice risk assessment

This dataset relates to a drone mapping campain on Gruvefjellet in Svalbard during 2022. Two campains were conducted, one in spring and one in summer. The objective of the campain was to investigate the size of the snow cornices on Gruvefjellet with respect to the risk of cornice-triggered avalanches. Mapping was conducted with a DJI Mavic 2 Pro Enterprise. Results contain a digital elevation model (DEM), an model (.STL and .PDF) with texture (.JPG), a tiled model that contains the same information as the model and texture in Agisoft tiled model format (.TLS, propritary Agisoft format), and a process report (.PDF/Archivable). The raw images are stored inside a zip file that has been split into multiple parts due to the large file size.

本数据集涉及于2022年在斯瓦尔巴德地区的Gruvefjellet山脉所进行的无人机测绘行动。该行动分为春季和夏季两个阶段。其目的是探究Gruvefjellet地区雪檐的大小，并评估其引发的雪崩风险。测绘工作采用了DJI Mavic 2 Pro Enterprise型号的无人机进行。数据成果包括数字高程模型（DEM）、包含纹理的模型（.STL和.PDF格式），以及包含与模型和纹理相同信息的分块模型（Agisoft分块模型格式.TLS，Agisoft专有格式），此外还包括了一份过程报告（.PDF/可存档格式）。由于文件体积庞大，原始图像被存储在一个已分割成多个部分的压缩文件中。
