Drone-based mapping of the Lagoon Pingo in Svalbard

This database contains a digital elevation model (DEM) and an orthomosaic map of the Lagoon Pingo in Svalbard. The DEM and orthomosaic were built from drone-based images and a structure from motion (SfM) method with Agisoft Metashape. The Lagoon Pingo is a coastal open-system pingo with year-round methane release located in the High Arctic fjord-valley of Adventdalen, Svalbard. This dataset depicts Lagoon Pingo in May 2020 at the end of the Spring season, whereby surface icings have developed following freezing of the perennial groundwater springs.

本数据库收录了斯瓦尔巴群岛泻湖冰核丘（Lagoon Pingo）的数字高程模型（digital elevation model, DEM）与正射影像图（orthomosaic map）。该数据集的数字高程模型与正射影像图基于无人机影像，通过运动恢复结构（structure from motion, SfM）方法结合Agisoft Metashape软件构建而成。泻湖冰核丘是一处坐落于斯瓦尔巴Adventdalen高北极峡湾谷地的沿海开放系统冰核丘，常年释放甲烷。本数据集呈现了2020年5月春季末期的泻湖冰核丘景象，彼时常年地下水泉经冻结后形成了表层积冰。
