Methods

ol.coordinate.add(coordinate, delta){ol.Coordinate}

src/ol/coordinate.js, line 41

Add delta to coordinate. coordinate is modified in place and returned by the function.

Example:

var coord = [7.85, 47.983333];
ol.coordinate.add(coord, [-2, 4]);
// coord is now [5.85, 51.983333]

Name	Type	Description
coordinate	ol.Coordinate	Coordinate.
delta	ol.Coordinate	Delta.

Returns:

The input coordinate adjusted by the given delta.

ol.coordinate.createStringXY(opt_fractionDigits){ol.CoordinateFormatType}

src/ol/coordinate.js, line 110

Returns a ol.CoordinateFormatType function that can be used to format a {ol.Coordinate} to a string.

Example without specifying the fractional digits:

var coord = [7.85, 47.983333];
var stringifyFunc = ol.coordinate.createStringXY();
var out = stringifyFunc(coord);
// out is now '8, 48'

Example with explicitly specifying 2 fractional digits:

var coord = [7.85, 47.983333];
var stringifyFunc = ol.coordinate.createStringXY(2);
var out = stringifyFunc(coord);
// out is now '7.85, 47.98'

Name	Type	Description
fractionDigits	number	The number of digits to include after the decimal point. Default is 0.

Returns:

Coordinate format.

ol.coordinate.format(coordinate, template, opt_fractionDigits){string}

src/ol/coordinate.js, line 165

Transforms the given ol.Coordinate to a string using the given string template. The strings {x} and {y} in the template will be replaced with the first and second coordinate values respectively.

Example without specifying the fractional digits:

var coord = [7.85, 47.983333];
var template = 'Coordinate is ({x}|{y}).';
var out = ol.coordinate.format(coord, template);
// out is now 'Coordinate is (8|48).'

Example explicitly specifying the fractional digits:

var coord = [7.85, 47.983333];
var template = 'Coordinate is ({x}|{y}).';
var out = ol.coordinate.format(coord, template, 2);
// out is now 'Coordinate is (7.85|47.98).'

Name	Type	Description
coordinate	ol.Coordinate | undefined	Coordinate.
template	string	A template string with {x} and {y} placeholders that will be replaced by first and second coordinate values.
fractionDigits	number	The number of digits to include after the decimal point. Default is 0.

Returns:

Formatted coordinate.

ol.coordinate.rotate(coordinate, angle){ol.Coordinate}

src/ol/coordinate.js, line 209

Rotate coordinate by angle. coordinate is modified in place and returned by the function.

Example:

var coord = [7.85, 47.983333];
var rotateRadians = Math.PI / 2; // 90 degrees
ol.coordinate.rotate(coord, rotateRadians);
// coord is now [-47.983333, 7.85]

Name	Type	Description
coordinate	ol.Coordinate	Coordinate.
angle	number	Angle in radian.

Returns:

Coordinate.

ol.coordinate.toStringHDMS(coordinate){string}

src/ol/coordinate.js, line 293

Example:

var coord = [7.85, 47.983333];
var out = ol.coordinate.toStringHDMS(coord);
// out is now '47° 59′ 0″ N 7° 51′ 0″ E'

Name	Type	Description
coordinate	ol.Coordinate | undefined	Coordinate.

Returns:

Hemisphere, degrees, minutes and seconds.

ol.coordinate.toStringXY(coordinate, opt_fractionDigits){string}

src/ol/coordinate.js, line 322

Example without specifying fractional digits:

var coord = [7.85, 47.983333];
var out = ol.coordinate.toStringXY(coord);
// out is now '8, 48'

Example explicitly specifying 1 fractional digit:

var coord = [7.85, 47.983333];
var out = ol.coordinate.toStringXY(coord, 1);
// out is now '7.8, 48.0'

Name	Type	Description
coordinate	ol.Coordinate | undefined	Coordinate.
fractionDigits	number	The number of digits to include after the decimal point. Default is 0.

Returns:

XY.
