Add XY Coordinates

Summary

Adds the fields POINT_X and POINT_Y to the point input features and calculates their values. It also appends the POINT_Zand POINT_M fields if the input features are Z- and M-enabled. Illustration

Usage

• If the POINT_X, POINT_Y, POINT_Z, and POINT_M fields exist, their values are recalculated.
• The output POINT_X and POINT_Y field values are based on the coordinate system of the dataset, not the coordinate system of the map display. To force the POINT_X and POINT_Y values to be in a coordinate system different than the input dataset, set the Output Coordinate System environment.
• If points are moved after using Add XY Coordinates, their POINT_X and POINT_Y values, and POINT_Z and POINT_M values—if present—must be recomputed by running Add XY Coordinates again.
• The Project tool does not modify the values of POINT_X, POINT_Y, POINT_Z, or POINT_M fields.
• If the input features are in a geographic coordinate system, POINT_X and POINT_Y represent the longitude and latitude, respectively.
