nearest_station: Find out neighborhood stations

Description

Return the nearest stations information to the given coordinates.

Usage

nearest_station(longitude, latitude, geometry = NULL)
pick_neighbor_stations(
  longitude,
  latitude,
  distance = 1,
  .unit = "m",
  geometry = NULL
)
pick_neighbor_tide_stations(
  year,
  longitude,
  latitude,
  distance = 100,
  .unit = "km",
  geometry = NULL
)

Value

an object of class sf.

Arguments

longitude

Longitude.

latitude

Latitude.

geometry

XY sf::sf object.

distance

Distance from station to station to adjustment.

.unit

Unit used for extraction from the point of interest. Default m (meters). This value is passed to units::as_units.

year

For tide level data. Restricted to the observation points in the target year.

Details

• nearest_station(): Return single station data.

• pick_neighbor_stations(): Pick-up neighbourhood stations.

• pick_neighbor_tide_stations(): Pick-up neighbourhood tidal observation stations. Filter by distance from target point.

Examples

nearest_station(142.9313, 43.70417)

pick_neighbor_stations(140.10, 36.08, 300000)

d <-
  pick_neighbor_stations(140.10, 36.08, 30, "km")
pick_neighbor_stations(geometry = sf::st_point(c(140.1833, 36.23333)),
                       distance = 100)

pick_neighbor_tide_stations(longitude = 133.4375, latitude = 34.45833,
                            year = 2020,
                            distance = 100, .unit = "km")
