# MapInverse Method

The MapInverse method transforms map coordinates from Cartesian (x, y) coordinates to longitude and latitude, using the map projection associated with the graphic.

## Example

See the example for the MapForward Method.

## Syntax

Result = graphic.MapInverse(X [, Y] [, /RADIANS])

## Return Value

The result is a (2, n) array containing the longitude/latitude coordinates.

## Arguments

### X

An n-element vector containing the x values. If the Y argument is omitted, X must be a (2, n) array of X and Y pairs.

### Y

An n-element vector containing y values. If this argument is omitted, X must be a (2, n) array of X and Y pairs.

## Keywords

### RADIANS

Set this keyword to indicate that the returned longitude and latitude coordinates should be expressed in radians. By default, returned coordinates are expressed in degrees.
