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 3^rd 2018, August 14^th 2019 and November 6^th 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.奥地利OAL地区活跃深层伏格尔贝格（Vögelsberg）滑坡的多时态数字地形模型，其空间分辨率为50厘米，坐标为北纬47.272°、东经11.597°。该栅格数据集由经分类的三维点云生成，点云数据由Riegl VUX-1LR无人机激光扫描仪分别于2018年8月3日、2019年8月14日及2020年11月6日采集，投影坐标系为EPSG 31254。地面点分类方法遵循Axelsson（2000）提出的分类标准。本数据集用于评估奥地利OAL地区活跃深层伏格尔贝格滑坡前缘的地形变化情况。
