Assign values in a new field based on values in another field for pop-ups with Arcade in ArcGIS Pro

Summary

In ArcGIS Pro, Arcade expressions can be used to create a new field with values assigned based on the values of another field. This is useful for classifying the values of a field into groups of values in a new field.

This articles provides an example and instruction using the Find() Arcade expression in ArcGIS Pro. In this example, the Arcade expression is used to create a new field called Make_Grouping with values assigned according to the values in the Make field, as seen in pop-up in the image below.

Procedure

1. Start ArcGIS Pro and open the project.
2. In the Contents pane, right-click the feature class, and click Configure Pop-ups to open the Configure Pop-ups pane.

3. Click Expressions, and click New.
4. In the Expression Builder dialog box, configure the following parameters for the Arcade expression.
   1. For Name, rename the new expression.
   2. For Title, specify a title for the new expression.
   3. For the Expression section, insert the following Arcade expression.

if (Find("<uniquePartOfFieldValue>", $feature.<fieldName>, 0)>-1) {
   return "<newFieldValue>";
} else if (Find("<uniquePartOfFieldValue1>", $feature.<fieldName>, 0)>-1) {
   return "<newFieldValue1>";
}

if (Find("Cl", $feature.Make, 0)>-1) {
   return "A";
} else if (Find("Io", $feature.Make, 0)>-1) {
   return "B";
} else if(Find("Ke", $feature.Make, 0)>-1) {
   return "C";
} else if(Find("Lu", $feature.Make, 0)>-1) {
   return "D";
} else if(Find("Mu", $feature.Make, 0)>-1) {
   return "E"
} else if(Find("Or", $feature.Make, 0)>-1) {
   return "F";
} else if(Find("Pa", $feature.Make, 0)>-1) {
   return "G";
} else if(Find("Wa", $feature.Make, 0)>-1) {
   return "H"
}

5. Click Verify to run a test of the expression. If the expression is valid, click OK.

6. In the Configure Pop-ups pane, click Back and click Edit pop-up element.

7. Ensure the newly created expression check box is checked in the Fields Options pane.

The newly configured pop-up below displays the newly added Make_Grouping field with assigned values in the pop-up after using the Arcade expression.
