Details

This function:

  • Uses {tigris} to get Washington county boundaries.

  • Downloads the full SWIFD dataset in GeoJSON format via {httr}.

  • Parses the JSON using {geojsonsf}.

  • Clips to the union of the selected counties, applying a small buffer to capture stream overlaps.

  • Optionally writes the result to disk as a Shapefile.

Examples

if (FALSE) { # \dontrun{

swifd_multi <- get_swifd_by_county(c("Columbia", "Garfield"))

get_swifd_by_county(c("Columbia", "Garfield"), save_path = "data/southwest_swifd")
} # }
