Package com.vaadin.flow.component.map.configuration

Class Coordinate

java.lang.Object

com.vaadin.flow.component.map.configuration.Coordinate

All Implemented Interfaces:

Serializable

public class Coordinate
extends Object
implements Serializable

Represents map coordinates in a specific projection. Which projection the coordinates are in is not known by the coordinate itself, and developers must ensure themselves to use the same projection between coordinates, the map viewport, and map sources.

Constructor Detail

Coordinate

public Coordinate()

Coordinate

public Coordinate(double x,
                  double y)

Constructs a new coordinate instance from x and y coordinates. Unless the map's view uses a custom projection, it is assumed that the coordinates are in EPSG:3857 / Web Mercator Sphere projection. To create coordinates from latitude and longitude, see fromLonLat(double, double).

Parameters:

x -

y -

getX

public double getX()

getY

public double getY()

fromLonLat

public static Coordinate fromLonLat(double longitude,
                                    double latitude)

Creates a coordinate from a longitude and latitude, and converts it into Projection.EPSG_3857 projection.

Parameters:

longitude - longitude value

latitude - latitude value

Returns:

coordinate in Projection.EPSG_3857 projection

fromLonLat

public static Coordinate fromLonLat(double longitude,
                                    double latitude,
                                    Projection targetProjection)

Creates a coordinate from a longitude and latitude, and converts it into the specified projection.

Currently, only converting into Projection.EPSG_3857 projection is supported.

Parameters:

longitude - longitude value

latitude - latitude value

targetProjection - the projection of the resulting coordinate

Returns:

coordinate in the specified projection
