To calculate the XY coordinates in the attribute table of a layer of points, you can do it with the Add XY Coordinates tool from ArcToolbox.
The steps to complete the calculation coordinates are:
- Before starting, you need to have defined the respective reference system.
- From ArcToolbox, go to Data Management Tools> Features> Add XY Coordinates.
- In the popup window select the points layer (shapefile), then accept.
- Open the attribute table of the point layer to display calculated fields.
To calculate geographical coordinates, it is necessary to add two type text fields (latitude/longitude), right-click on the field and select Calcutate Geometry (X Coordinate Point to Longitude, Y Coordinate Point Latitude), in Units select the format of the coordinates geographical.
