Dataset of "Historical aerial image photogrammetry for tracking past deformation of Reissenschuh deep-seated rock slide in Tyrol, Austria."

This dataset features monitoring data of the Reissenschuh deep-seated rock slide (Tyrol, Austria) and consists of: OVERVIEW: point_clouds : point clouds derived from historical aerial image photogrammetry (1954, 1973, 2007, 2010, 2019) in the geospatial point cloud format LAZ (LASZip). raster : RS_DSM_stack: used for applying the image correlation technique to derive displacement vectors. gridded photogrammetic point clouds (1954, 1973, 2007, 2010, 2019) gridded airborne laser scanning data (2008, 2021) RS_DSM_HS_stack: Shaded ambient occlusion reliefs computed from the multitemporal DSMs, which were used for applying the image correlation technique to derive displacement vectors.

RS_DoD_stack : digital surface models of difference computed by subtracting the subsequent DSMs. The uncertainty of the individual DoDs are masked. RS_velocity_epoch_stack : gridded velocity vectors (m/yr) computed from the displacement vectors by dividing the vector length by the time period between the acquisition campaigns RS_1954_2021_stack : gridded mean velocity vectors (m/yr) computed from the displacement vectors by dividing the vector length by the total period between first and last acquisition campaign and respective acceleration. shapefiles : points DGNSS (DGNSS_points) manual blocktracking on the historical orthoimagery (blocktracking_points) displacement vectors correlation points derived from image correlation techniques (IMCORR_points) displacement vectors correlation points derived from image correlation techniques (first to last acquisition campaign) (IMCORR_filtered_points) lines filtered displacement vectors derived from image correlation techniques (IMCORR_time_series_1954_2021_5m_filtered) polygon Outline of active unit (outline_RS) Delineation of subunits (units) Further details The airborne laser scanning data from 2008 and 2021 were provided by the Federal Government of Tyrol - data.tirol.gv.at and are licenced under CC BY 4.0 (creativecommons.org/licenses/by/4.0/deed.de) and must be used according to the following conditions of use: tirol.gv.at/data/nutzungsbedingungen/ The source images (1954) used for photogrammetry are © Federal Office of Metrology and Surveying.
