hwsd_download(ws_path = "D:/data/HWSD2", verbose = TRUE)

# Dominant-component values (default)
pt <- hwsd_extract(
  coords = c(110, 40),
  param = c("SAND", "PH_WATER"),
  layer = "D1",
  ws_path = "D:/data/HWSD2"
)

# Share-weighted synthesis (use hwsd_compose)
props <- hwsd_props()
pt_syn <- hwsd_compose(
  coords = c(110, 40),
  param = c("SAND", "PH_WATER"),
  layer = "D1",
  ws_path = "D:/data/HWSD2",
  props = props
)

Notes

• More tutorials and documentation: https://rimagination.github.io/tidyhwsd
• Set WS_PATH in ~/.Renviron to avoid passing ws_path every time.
• If downloads are slow, manually download and extract the grid zip so HWSD2.bil exists: https://s3.eu-west-1.amazonaws.com/data.gaezdev.aws.fao.org/HWSD/HWSD2_RASTER.zip
