rnrfa (version 0.5.4)

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)
# ## End(Not run)
