2023 Glacier surface elevation data from airborne laser scanner survey in Svalbard@en

This dataset contains high resolution surface elevation data of glaciers in Svalbard, collected in aerial surveys of the research aircraft Polar 5. The elevation and near infrared reflectivities provided by the airborne laser scanner RIEGEL VQ-580 are made available as rasterized digital elevation models. The focus during the acquisition was on glaciers with dynamic behavior such as glacial surges. Therefore, the covered area mostly includes selected individual glaciers that were surveyed in July and August 2023. In the region of Heer Land the glaciers Vallåkrabreen, Mettebreen, Ragna-Mariebreen and Scheelebreen are covered. Further, the glaciers Borebreen, Slakbreen and Blankfjellbreen (tributary of Nathorstbreen) were all surveyed. […]本数据集涵盖斯瓦尔巴群岛（Svalbard）冰川的高分辨率地表高程数据，相关数据由科研飞机“极地5号（Polar 5）”开展的航空测量采集获取。机载激光扫描仪RIEGEL VQ-580所采集的高程与近红外反射率数据，以栅格化数字高程模型（Digital Elevation Model，DEM）的形式对外共享。数据采集阶段的重点聚焦于具备动态运动特征的冰川（如冰川跃动（glacial surges）），因此本次覆盖区域主要包含2023年7月至8月期间完成测量的选定单条冰川。在海尔兰（Heer Land）区域，覆盖了瓦拉克勒布雷恩冰川（Vallåkrabreen）、梅特布雷恩冰川（Mettebreen）、拉格纳-玛丽布雷恩冰川（Ragna-Mariebreen）以及舍勒布雷恩冰川（Scheelebreen）；此外，博雷布雷恩冰川（Borebreen）、斯拉克布雷恩冰川（Slakbreen）以及布兰克费尔勒布雷恩冰川（Blankfjellbreen，纳斯托斯特布雷恩冰川（Nathorstbreen）的支流）均完成了测量。[…]
