收藏资源简介：
Supplement to Jackisch et al., 2021: Drone-based magnetic and multispectral surveys to develop a 3D model for mineral exploration at Qullissat, Disko Island, Greenland. https://se.copernicus.org/articles/13/793/2022/se-13-793-2022.html Data set contains 3D model in dxf file, additional images, selected handheld spectra. Publication summary: We integrate UAS-based magnetic and remote sensing mineral exploration data with legacy exploration data of a Ni-Cu-PGE prospect on Disko Island, West Greenland. The basalt unit has a complex magnetization, and we use a 3D magnetic vector inversion on the UAS magnetics to estimate magnetic properties and spatial dimensions of the mineralized unit. Our 3D modelling reveals a horizontal sheet and a strong remanent magnetization component. We highlight the advantage of UAS in rugged terrain. Jackisch, R., Heincke, B.

本数据集为Jackisch等人2021年研究的补充数据集：基于无人机的磁法与多光谱调查，用于格陵兰迪斯科岛Qullissat地区矿产勘探三维模型构建。 https://se.copernicus.org/articles/13/793/2022/se-13-793-2022.html 本数据集包含绘图交换格式（Drawing Exchange Format, DXF）的三维模型、辅助影像及精选手持光谱数据。 研究概述： 我们将基于无人机系统（Unmanned Aircraft System, UAS）的磁法与遥感矿产勘探数据，与西格陵兰迪斯科岛一处镍-铜-铂族元素（Nickel-Copper-Platinum Group Elements, Ni-Cu-PGE）矿点的遗留勘探数据进行整合。该玄武岩单元具有复杂的磁化特性，我们针对无人机系统磁测数据开展三维磁矢量反演，以估算矿化单元的磁性特征与空间展布范围。本次三维建模结果显示存在一套近水平薄板状矿体，且具有显著的剩余磁化分量。我们论证了无人机系统在崎岖地形作业中的显著优势。 Jackisch, R., Heincke, B.
