add_geolocate_control function

Add a geolocate control to a map

This function adds a Geolocate control to a Mapbox GL or MapLibre GL map. The geolocate control allows users to track their current location on the map.

add_geolocate_control(
  map,
  position = "top-right",
  track_user = FALSE,
  show_accuracy_circle = TRUE,
  show_user_location = TRUE,
  show_user_heading = FALSE,
  fit_bounds_options = list(maxZoom = 15),
  position_options = list(enableHighAccuracy = FALSE, timeout = 6000)
)

Arguments

• map: A map object created by the mapboxgl or maplibre functions.
• position: The position of the control. Can be one of "top-left", "top-right", "bottom-left", or "bottom-right". Default is "top-right".
• track_user: Whether to actively track the user's location. If TRUE, the map will continuously update as the user moves. Default is FALSE.
• show_accuracy_circle: Whether to show a circle indicating the accuracy of the location. Default is TRUE.
• show_user_location: Whether to show a dot at the user's location. Default is TRUE.
• show_user_heading: Whether to show an arrow indicating the device's heading when tracking location. Only works when track_user is TRUE. Default is FALSE.
• fit_bounds_options: A list of options for fitting bounds when panning to the user's location. Default maxZoom is 15.
• position_options: A list of Geolocation API position options. Default has enableHighAccuracy=FALSE and timeout=6000.
