rnrfa (version 1.5.0)

catalogue: List of stations from UK NRFA

Description

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

Usage

catalogue(bbox = NULL, columnName = NULL, columnValue = NULL,
  minRec = NULL, all = TRUE)

Arguments

bbox

this is a geographical bounding box (e.g. list(lonMin=-3.82, lonMax=-3.63, latMin=52.43, latMax=52.52))

columnName

name of column to filter

columnValue

string to search in columnName

minRec

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, operator, haName, catchmentArea, altitude, lat, lon.

Value

data.frame with 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.

Offline you can browse the cached version running the command data(stationSummary)

Examples

# NOT RUN {
  # Retrieve all the stations in the network
  x <- catalogue()

  # Define a bounding box:
  bbox <- list(lonMin=-3.82, lonMax=-3.63, latMin=52.43, latMax=52.52)
  # Get stations within the bounding box
  x <- catalogue(bbox)

  # Get stations based on minimum number of recording years
  x <- catalogue(minRec=30)
# }
# NOT RUN {
# }
