# Coordinate An object representing the latitude and longitude for a point on the Earth’s surface. ``` class Coordinate implements CoordinateData ``` ## Overview A [`Coordinate`](/documentation/MapKitJS/Coordinate) is a point on a spherical representation of the Earth at a specific degree of latitude (`90` and -`90`) and longitude (`180` to -`180`) that you use to search for locations, place annotations, and other objects on the map. ## Topics ### Creating a coordinate [`constructor(latitude?: number, longitude?: number);`](/documentation/MapKitJS/Coordinate/CoordinateConstructor) Creates a coordinate object with the specified latitude and longitude. [`interface CoordinateData`](/documentation/MapKitJS/CoordinateData) A plain object representation of a coordinate. ### Defining the coordinates [`latitude: number;`](/documentation/MapKitJS/Coordinate/latitude) The latitude, in degrees. [`longitude: number;`](/documentation/MapKitJS/Coordinate/longitude) The longitude, in degrees. ### Comparing, copying, and converting coordinates [`copy(): Coordinate;`](/documentation/MapKitJS/Coordinate/copy) Returns a copy of the coordinate. [`equals(anotherCoordinate: CoordinateData): boolean;`](/documentation/MapKitJS/Coordinate/equals) Returns a Boolean value indicating whether two coordinates are equal. [`toMapPoint(): MapPoint;`](/documentation/MapKitJS/Coordinate/toMapPoint) Returns the map point that corresponds to the coordinate. [`toUnwrappedMapPoint(): MapPoint;`](/documentation/MapKitJS/Coordinate/toUnwrappedMapPoint) Returns the unwrapped map point that corresponds to the coordinate. ### Instance Methods [`toString(): string;`](/documentation/MapKitJS/Coordinate/toString) Returns a string representation of the coordinate object. ## Relationships ### Conforms To [`CoordinateData`](/documentation/MapKitJS/CoordinateData) --- Copyright © 2026 Apple Inc.
