Adding x,y Coordinates to a table in ArcMap

This procedure outlines the steps necessary to add X,Y coordinates to a table for a point data file in ArcMap. The example used in this procedure is a set of points created from a table of latitude and longitude values. The data was converted to a UTM projection and this procedure will create 2 new columns holding the UTM eastings and northings for the point data.

Setting up the data file

The table should resemble the following image.

Latitude 43 degrees UTM-Y 4,763,000 metres N
Longitude -79 degrees UTM-X 623,000 metres E


Updating the column with UTM coordinates

The Field Calculator appears.

Click OK to run the equation. The table will update with UTM X coordinates.

The final step is to save the changes made to the table.
