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 )
| 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, operator, haName, catchmentArea, altitude, lat, lon. |
tibble table containing the list of stations and related metadata
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.
