List of stations from UK NRFA

This function pulls the list of stations (and related metadata), falling within a given bounding box, from the CEH National River Flow Archive website.

catalogue(
  bbox = NULL,
  column_name = NULL,
  column_value = NULL,
  min_rec = NULL,
  all = TRUE
)

Arguments

bbox

this is a geographical bounding box (e.g. list(lon_min = -3.82, lon_max = -3.63, lat_min = 52.43, lat_max = 52.52))

column_name

name of column to filter

column_value

string to search in column_name

min_rec

minimum number of recording years

all

if TRUE it returns all the available metadata. If FALSE, it returns only the following columns: id, name, river, hydrometricArea, catchmentArea, lat, lon, selected feh catchment descriptors.

Value

tibble table containing the list of stations and related metadata

Details

coordinates of bounding box are required in WGS84 (EPSG: 4326). If BB coordinates are missing, the function returns the list corresponding to the maximum extent of the network.

Examples

if (FALSE) {
  # Retrieve all the stations in the network
  x <- catalogue()

  # Define a bounding box:
  bbox <- list(lon_min=-3.82, lon_max=-3.63, lat_min=52.43, lat_max=52.52)
  # Get stations within the bounding box
  x <- catalogue(bbox)

  # Get stations based on minimum catchment area
  x <- catalogue(column_name = "catchment-area", column_value = 2000)

  # Get stations based on minimum number of recording years
  x <- catalogue(min_rec=30)
}
