Geographic types and constructors.

Latitude/Longitude


type alias LatLng =
Maps.Internal.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 : Basics.Float -> Basics.Float -> LatLng

Create a LatLng.

For example:

latLng 45 -175

Bounds


type alias Bounds =
Maps.Internal.Bounds.Bounds

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

NorthEast/SouthWest bounds

@docs bounds

Center and Zoom Level

@docs centerBounds

bounds : { 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 : Basics.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)
