LatLng

Represents a geographical point with a certain latitude and longitude.

Usage example

var latlng = L.latLng(50.5, 30.5);

All Leaflet methods that accept LatLng objects also accept them in a simple Array form and simple object form (unless noted otherwise), so these lines are equivalent:

map.panTo([50, 30]);
map.panTo({lon: 30, lat: 50});
map.panTo({lat: 50, lng: 30});
map.panTo(L.latLng(50, 30));

Creation

Factory Description
L.latLng(<Number> latitude, <Number> longitude, <Number> altitude?) Creates an object representing a geographical point with the given latitude and longitude (and optionally altitude).
L.latLng(<Array> coords) Expects an array of the form [Number, Number] or [Number, Number, Number] instead.
L.latLng(<Object> coords) Expects a plain object of the form {lat: Number, lng: Number} or {lat: Number, lng: Number, alt: Number} instead.

Methods

Method Returns Description
equals(<LatLng> otherLatLng, <Number> maxMargin?) Boolean

Returns true if the given LatLng point is at the same position (within a small margin of error). The margin of error can be overriden by setting maxMargin to a small number.

toString() String

Returns a string representation of the point (for debugging purposes).

distanceTo(<LatLng> otherLatLng) Number

Returns the distance (in meters) to the given LatLng calculated using the Haversine formula.

wrap() LatLng

Returns a new LatLng object with the longitude wrapped so it's always between -180 and +180 degrees.

toBounds(<Number> sizeInMeters) LatLngBounds

Returns a new LatLngBounds object in which each boundary is sizeInMeters meters apart from the LatLng.

Properties

lat Number Latitude in degrees
lng Number Longitude in degrees
alt Number Altitude in meters (optional)
