Extract HUC IDs at point locations. Returns a data.frame object containing locs_id and HUC IDs.

Usage

calculate_huc(from, locs, locs_id = "site_id", geom = FALSE, ...)

Arguments

from

SpatVector(1). Output from process_huc().

locs

data.frame. character to file path, SpatVector, or sf object.

locs_id

character(1). Column within locations CSV file containing identifier for each unique coordinate location.

Examples

## NOTE: Example is wrapped in `\dontrun{}` as function requires a large
##       amount of data which is not included in the package.
if (FALSE) { # \dontrun{
loc <- data.frame(id = "001", lon = -78.90, lat = 35.97)
calculate_huc(
  from = huc, # derived from process_huc() example
  locs = loc,
  locs_id = "id",
  geom = FALSE
)
} # }
