A high-frequency and high-resolution image time series of the Gornergletscher - Swiss Alps - derived from repeated UAV surveys

This dataset is based on aerial photographs of the Gornergletscher glacial system (Switzerland) collected during ten intensive UAV surveys carried out approximately every two weeks throughout the summer 2017. The final products consist in a series of 10 cm resolution ortho-images, Digital Elevation Models of the glacier surface, and Matching Maps that can be used to quantify ice surface displacements.本数据集基于2017年夏季每间隔约两周开展的10次密集无人机（Unmanned Aerial Vehicle, UAV）航拍作业所采集的瑞士戈尔纳冰川（Gornergletscher）系统航拍影像构建而成。 最终成果包含一系列分辨率为10厘米的正射影像（Ortho-images）、冰川表面数字高程模型（Digital Elevation Model, DEM），以及可用于量化冰面位移的匹配图（Matching Maps）。
