How to Add Coordinates to an ArcMap

Adding Coordinates to ArcMap

• 1

  In ArcMap, click the "Add Data" button. Select the data point file you are working with.

• 2

  Make sure the projection of your data point file is in UTM projection by right-clicking "Layers," then selecting "Properties." Under the "Coordinate System" tab you can see what projection system is in use. Click "OK" to return to Map View.

• 3

  Open the "Attribute Table" for your point layer by right-clicking on the layer.

• 4

  Add the X coordinate field in the Attribute Layer by clicking "Options," then "Add Field." Repeat this step for the Y coordinate field.

• 5

  Calculate the coordinates based on your point data file by right-clicking "UTM-X" header and selecting "Calculate Values." In the Field Calculator, enter the following equation:

  Dim dblX as double

  Dim pPoint as IPoint

  Set pPoint = [Shape]

  dblX = pPoint.X

  Click "OK" and the equation will run and fill in your X coordinate data.

• 6

  Repeat Step 5 for the Y coordinate column, replacing "X" in the equation with "Y".

  Dim dblY as double

  Dim pPoint as IPoint

  Set pPoint = [Shape]

  dblX = pPoint.Y

  Make sure to save your new coordinate data set.
