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 1_mr_met.csv: Elevation and mean slope for mountain region areas in cities 2_uc_met.csv: Elevation and mean slope for urban centers (defined by in the GHSL data) in cities Standard deviation analysis derived from SRTM and processed in Google Earth Engine for mean slope in mountain regions and urban centers in cities: gee_sd gee_mr.csv: Mean slope and standard deviation for mountain region gee_uc.csv: Mean slope and standard deviation for urban centers (defined by in the GHSL data) Summary overview of cities with large landslides used in this study: cities_summary.csv Variables in this file are: eFUA_name := City name cntry := Country name cntry_ISO := Country ISO code fua_area := Estimate of total metropolitan city area (km^2) ls_total_area := Total large landslide areas within city (m^2) ls_pct_fua_area := Mapped large landslides\n(% of the metropolitan city area) pop_FUA_2015 := Metropolitan population estimate (2015) pop_ls := Estimate of total number of people on large landslides
