Terrestrial laser scanning data of the Äußeres Hochebenkar rock glacier close to Obergurgl, Austria acquired during the Innsbruck Summer School of Alpine Research

Permafrost phenomena like active rock glaciers are increasingly mapped and monitored with close range sensing techniques. Multi temporal and precise point clouds in high spatial resolution as they can be acquired by Terrestrial Laser Scanning (TLS), offer promising opportunities for detailed morphological analysis. Current research focuses on the quantification of morphological changes using objects moving with the surface of a creeping rock glacier. This data publication contains georeferenced (WGS 84 / UTM zone 32N; EPSG:32632) point clouds covering the tongue of the Äußeres Hochebenkar rock glacier located about 2 km south of Obergurgl. Point clouds were acquired using a TLS from different scan positions around the rock glacier during the Innsbruck Summer School of Alpine Research - "Close Range Sensing Techniques in Alpine Terrain".

诸如活动岩冰川的多年冻土现象，正愈发多地通过近距感测技术开展制图与监测工作。通过地面激光扫描（Terrestrial Laser Scanning, TLS）可获取高空间分辨率的多时态高精度点云，这类数据为精细化形态学分析提供了极具潜力的技术路径。当前相关研究聚焦于依托随蠕滑岩冰川表面运动的地物，开展冰川形态变化的量化分析工作。本数据集包含经过地理配准的点云数据，其坐标系采用WGS 84 / UTM 第32北带（EPSG:32632），覆盖了位于奥伯古格尔（Obergurgl）以南约2公里处的Äußeres Hochebenkar岩冰川的冰舌区域。本次点云数据采集工作，是在因斯布鲁克高山研究暑期学校——“高山地形近距感测技术”课程期间，通过TLS在该岩冰川周边的多个扫描站位完成的。
