Multi-temporal digital terrain models of the active deep-seated Vögelsberg landslide (OAL-Austria)

Multi-temporal digital terrain models of the active deep-seated Vögelsberg landslide in OAL Austria (Lat: 47.272°, Lon: 11.597°) with a spatial resolution of 50cm. Raster were derived from classified 3D point clouds acquired with a Riegl VUX-1LR unmanned aerial vehicle laser scanner on August 3rd 2018, August 14th 2019 and November 6th 2020 (Projection: EPSG 31254). Ground classification after Axelsson (2000). Data was used to assess topographic changes at the toe of the active deep-seated Vögelsberg landslide in OAL-Austria.

本数据集为奥地利OAL区域内沃格尔贝格（Vögelsberg）活动深层滑坡（坐标：纬度47.272°，经度11.597°）的多时序数字地形模型，空间分辨率达50厘米。该栅格数据源自2018年8月3日、2019年8月14日及2020年11月6日由瑞格（Riegl）VUX-1LR无人机激光扫描仪采集的分类三维点云，投影坐标系为EPSG 31254。地面点分类方法遵循Axelsson（2000）提出的技术方案。本数据集用于评估奥地利OAL区域沃格尔贝格活动深层滑坡前缘的地形变化情况。
