Maps.Geo

Geographic types and constructors.

Latitude/Longitude

type alias LatLng =

LatLng

The LatLng type is a simple record containing latitude and longitude.

You can create a longitude in two equivalent ways:

Maps.Geo.latLng 10 -80 == { lat = 10, lng = -80}

latLng : Float -> Float -> LatLng

Create a LatLng.

For example:

latLng 45 -175

type alias Bounds =

Bounds

The Bounds type has several variations. All of them can be used to calculate the position and zoom of a map.

@docs bounds

@docs centerBounds

{ northEast : LatLng

, southWest : LatLng

}

-> Bounds

Create a Bounds using a northeast and southwest point.

For example, the bounds of Ecuador

ecuador =
  bounds
    { northEast = latLng 1.4284875 -75.188794
    , southWest = latLng -5.0143511 -81.08498089999999
    }

centeredBounds : Float -> LatLng -> Bounds

Create a Bounds centered on a location with a given zoom level.

For example, zoomed into the streets of Baku, Azerbaijan:

baku =
  centeredBounds
    14
    (latLng 40.409264 49.867092)
