Adds the fields POINT_X and POINT_Y to the point input features and calculates their values. It also appends the POINT_Z and POINT_M fields if the input features are Z- and M-enabled.
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.
This tool modifies the input data. See Tools with no outputs for more information and strategies to avoid undesired data changes.
The point features whose x,y coordinates will be appended as POINT_X and POINT_Y fields.
The following Python window script demonstrates how to use the AddXY function in immediate mode.
import arcpy from arcpy import env env.workspace = "C:/data" arcpy.Copy_management("climate.shp", "climateXYpts.shp") arcpy.AddXY_management("climateXYpts.shp")
The following Python script demonstrates how to use the AddXY function in a stand-alone script.
# Name: AddXY_Example2.py # Description: Adding XY points to the climate dataset # Import system modules import arcpy from arcpy import env # Set workspace env.workspace = "C:/data" # Set local variables in_data= "climate.shp" in_features = "climateXPpts2.shp" # Copying data to preserve original dataset # Execute Copy arcpy.Copy_management(in_data, in_features) # Execute AddXY arcpy.AddXY_management(in_features)
