Hourly Terrestrial Laser Scanning Point Clouds of Snow Cover in the Area of the Schneeferner, Zugspitze, Germany

The near-continuous time series of point clouds was acquired in the snow-covered area of the Schneeferner at the Zugspitze mountain in Germany using hourly terrestrial laser scanning (TLS) over a period of five days in April 2018. The dataset comprises around 130 epochs of 10 to 25 million points per scan with centimeter-scale accuracy and point spacing. The 4D geospatial dataset of the experimental near-continuous laser scanning setup can be used for analysis of snow cover dynamics and in general method development for change analysis of natural scenes using laser scanning time series.

3D point cloud of the Hundsalm ice cave

3D point cloud of the Hundsalm ice cave acquired with a Riegl VZ-2000i Terrestrial Laser Scanner on 2020-05-15, 2020-06-23 and 2020-07-03. Individual point clouds acquired from 255 scan positions were co-registered taking into account potential changes in snow, firn and ice content between the acquisition campaigns. The final data set reflects the snow, firn and ice conditions of 2020-07-03 and contains 3D points with an average spatial resolution of 2 cm. Points are classified into 4 classes: 1 = above ground points (e.g. vegetation) outside the cave, 2 = ground points outside the cave, 3 = points representing the cave's rock surface, 4 = points representing the snow, firn and ice surface in the cave. The points are stored in ETRS89/UTM zone 32N coordinates (EPSG:25832) and include, beside of the classification, an intensity attribute.
