Large Landslide Exposure in Metropolitan Cities

These datasets (.Rmd, .Rroj., .rds) are ready to use within the R software for statistical programming with the R Studio Graphical User Interface (https://posit.co/download/rstudio-desktop/). Please copy the folder structure into one single directory and follow the instructions given in the .Rmd file. Files and data are listed and described as follows:

Main directory files: results_fpath

• Code containing statisticla analysis and ploting: 20240927_code.Rmd 
• 1_melted_lan_df.rds: Landslide time series database covering 1,085 landslides intersected with settlement footprints from 1985-2015.
• 4_cities_lan.df.rds: City and landslide data for these 1,085 landslides intersected with settlement footprints from 1985-2015.
• 7_zoib_nested_pop_pressure_model: brms statistical model file.
• ghs_stat_fua_comb.gpkg: Urban center data from the GHSL - Global Human Settlement Layer.

Population estimation files: wpop_files 

• 2015_ls_pop.csv: Estimates of population on landslides using the 100x100 population density grid from the WorldPop dataset.

Steepness and elevation analysis derived from SRTM and processed in Google Earth Engine for landslides, mountain regions and urban centers in cities: gee_files
