Coordinate class

The base coordinate class, used by all feature types. It's used to represent a point in geographic coordinates.

Example:

Coordinate(1, 2); // Coordinate(1, 2)
Coordinate(1, 2).toWKT(); // 1 2
Coordinate(1, 2).toJson(); // [1, 2]

Constructors

Coordinate(double latitude, double longitude)
Coordinate.fromJson(List<double> json)
Creates a Coordinate from a JSON List.
factory
Coordinate.fromWKT(String wkt)
Creates a Coordinate from a WKT String.
factory
Coordinate.random()
Returns a random Coordinate. This is useful for testing.

Methods

bearingTo(Coordinate other, {AngleUnit? unit}) → double
Returns the bearing to a different Coordinate in degrees, or specified unit. Uses the Haversine formula to calculate the bearing between two points.
destination(double distance, double bearing) → Coordinate
Returns the Coordinate at a certain distance and bearing from the Coordinate. distance is in meters and bearing is in degrees. Uses the Haversine formula to calculate the new coordinate.
distanceTo(Coordinate other, {DistanceUnit? unit}) → double
Returns the distance to a different Coordinate in meters or specified unit. Uses the Haversine formula to calculate the distance between two points.
interpolate(Coordinate to, double fraction) → Coordinate
Returns the Coordinate at a certain fraction of the distance between the Coordinate and different Coordinate, to. Uses the Haversine formula to calculate the new coordinate. The fraction is a number between 0 and 1. If the fraction is 0, the Coordinate will be the same as the Coordinate. If the fraction is 1, the Coordinate will be the same as the to.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toENU(Coordinate origin) → List<double>
Converts the Coordinate to a ENU List with a specified origin.
toJson() → List<double>
Converts the Coordinate to a JSON coordinate List.
toString() → String
A string representation of this object.
override
toWKT() → String
Converts the Coordinate to a WKT String. Useless on its own, but useful for other classes.

Operators

operator ==(Object other) → bool
The equality operator.
