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 and velocities.本数据集由2017年夏季期间每约两周开展一次的十次高密度无人机（Unmanned Aerial Vehicle, UAV）航拍测量所采集的瑞士戈尔纳冰川（Gornergletscher）冰体系统航空影像构建而成。最终产出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 Models, DEM），以及可用于量化冰面位移与流速的匹配图（Matching Maps）。
