Common Field Calculations in ArcGIS

Mar 6, 2019 ArcGIS-Desktop Python

The ArcGIS field calculator can save a person time and allow for fairly quick data cleanup IF you can remember how to use it. I don’t know about you, but for me the layout of the field calculator, the separation of the formula field and the code block area and the minor changes from standard Python formatting are enough to send me straight to the Google search bar if I haven’t used it in a while. That’s why I started making notes for even the simplest of tasks. I go back to them often saving myself time and frustration.

Maybe someday I’ll memorize these, but for now this works.

Below you’ll find a list of some simple field calculations that I use often as a starting place. I’ll add to these as I think of them. Maybe you’ll find one useful.
