By adding the new columns and using Calculate Geometry instead of the Field Calc the user only needs to make sure that the Data Frame is in the proper coordinate system - in this case NAD83. | |
| Nov 24, 2014 at 23:15 | comment | added | Chris W | @WolverineTime The answer is a bit confusing in that you don't access the Field Calculator per se. To add XY coordinates you actually Calculate Geometry (another choice when you right-click a column heading in an attribute table). | |
| Nov 18, 2014 at 18:18 | comment | added | WolverineTime | Hi user23715, I appreciate your suggestion of using the Field Calculator. Alas, I am still at a level in which I do not know what to actually input in the field calculator, so that it outputs the newly transformed lat/long. | |
| Nov 14, 2014 at 20:56 | comment | added | user23715 | @WolverineTime - YW. mkennedy's suggestion is faster/better for most applications. I should've mentioned it for a more complete answer. NOTE: Using the Field Calculator allows one to customize the field "values" and the Add XY Coords tool does not. Also using the tool may overwrite existing values - which can be good if you want it and quite bad if you don't. | |
| Nov 14, 2014 at 19:53 | comment | added | WolverineTime | You both gave great advice. I found the tool for "Add XY Coordinates (Data Management)." I ended up using that but also did a quick practice with the Field Calculator, in case I go that route in the future. Thanks! | |
| Nov 14, 2014 at 18:22 | comment | added | mkennedy | There also a tool, Add XY Coordinates. | |
