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)
