Coordinates

LatLng class

google.maps.LatLng class

A LatLng is a point in geographical coordinates: latitude and longitude.

• Latitude ranges between -90 and 90 degrees, inclusive. Values above or below this range will be clamped to the range [-90, 90]. This means that if the value specified is less than -90, it will be set to -90. And if the value is greater than 90, it will be set to 90.
• Longitude ranges between -180 and 180 degrees, inclusive. Values above or below this range will be wrapped so that they fall within the range. For example, a value of -190 will be converted to 170. A value of 190 will be converted to -170. This reflects the fact that longitudes wrap around the globe.

Although the default map projection associates longitude with the x-coordinate of the map, and latitude with the y-coordinate, the latitude coordinate is always written first, followed by the longitude.
Notice that you cannot modify the coordinates of a LatLng. If you want to compute another point, you have to create a new one.

Most methods that accept LatLng objects also accept a LatLngLiteral object, so that the following are equivalent:

 map.setCenter(new google.maps.LatLng(-34, 151));
 map.setCenter({lat: -34, lng: 151}); 

The constructor also accepts LatLngLiteral and LatLng objects. If a LatLng instance is passed to the constructor, a copy is created.

The possible calls to the constructor are below:

 new google.maps.LatLng(-34, 151);
 new google.maps.LatLng(-34, 151, true);
 new google.maps.LatLng({lat: -34, lng: 151});
 new google.maps.LatLng({lat: -34, lng: 151}, true);
 new google.maps.LatLng(new google.maps.LatLng(-34, 151));
 new google.maps.LatLng(new google.maps.LatLng(-34, 151), true);
 

Access by calling const {LatLng} = await google.maps.importLibrary("core"). See Libraries in the Maps JavaScript API.

Constructor

Latitude is specified in degrees within the range [-90, 90]. Longitude is specified in degrees within the range [-180, 180). Set noClampNoWrap to true to enable values outside of this range. Note the ordering of latitude and longitude.

LatLngLiteral interface

google.maps.LatLngLiteral interface

Object literals are accepted in place of LatLng objects, as a convenience, in many places. These are converted to LatLng objects when the Maps API encounters them.

Examples:

 map.setCenter({lat: -34, lng: 151});
 new google.maps.Marker({position: {lat: -34, lng: 151}, map: map}); 

LatLng object literals are not supported in the Geometry library.

Properties
lat	Type:  number Latitude in degrees. Values will be clamped to the range [-90, 90]. This means that if the value specified is less than -90, it will be set to -90. And if the value is greater than 90, it will be set to 90.
lng	Type:  number Longitude in degrees. Values outside the range [-180, 180] will be wrapped so that they fall within the range. For example, a value of -190 will be converted to 170. A value of 190 will be converted to -170. This reflects the fact that longitudes wrap around the globe.

LatLngBounds class

LatLngAltitude class

google.maps.LatLngAltitude class

A LatLngAltitude is a 3D point in geographical coordinates: latitude, longitude, and altitude.

• Latitude ranges between -90 and 90 degrees, inclusive. Values above or below this range will be clamped to the range [-90, 90]. This means that if the value specified is less than -90, it will be set to -90. And if the value is greater than 90, it will be set to 90.
• Longitude ranges between -180 and 180 degrees, inclusive. Values above or below this range will be wrapped so that they fall within the range. For example, a value of -190 will be converted to 170. A value of 190 will be converted to -170. This reflects the fact that longitudes wrap around the globe.
