MapXYToCoord()
Summary
Translates a local map X-Y coordinate to a longitude-latitude coordinate.
Syntax
c = MapXYToCoord(string map_name, array x_and_y)
| Argument | Contents |
|---|---|
| map_name | The map whose coordinate system is used |
| x_and_y | A two-element array containing the x-value and y-value of the coordinate to be translated |
Returns
A coordinate indicating the longitude and latitude of the point.
Notes
-
The values of x and y should be real numbers in the units specified by the map's coordinate system.
-
If the map_name is null, the current map is used.
-
The map should be displayed using a coordinate system. If only a projection is used, the result is unspecified.
-
For more details on coordinate systems, see Using Projections and Coordinate Systems.
