Display a count of different point features in a selected polygon through a pop-up using ArcGIS Arcade in ArcGIS Online

Summary

In ArcGIS Online, the total number of different point features can be determined in a selected polygon. This provides a visual representation to differentiate the total number of businesses and facilities in a selected region. It also enhances the clarity of information when analyzing the map.

This article provides the workflow to display a count of different point features in a selected polygon through a pop-up using ArcGIS Arcade in ArcGIS Online. In this workflow, Point1, Point2 and Point3 are different point layers while Polygon1 is the polygon layer as shown in the image below.

Procedure

1. In ArcGIS Online Map Viewer, open the web map containing the features.
2. On the Contents (dark) toolbar, click Layers to open the Layers pane and select the polygon layer with the pop-up intended to be configured.
3. On the Settings (light) toolbar, click Pop-ups.
4. In the Pop-ups pane, click Attribute expressions under Options.
5. In the Attribute expressions pane, click + Add expression.
6. In the editor window, create a name for the Arcade expression and specify the Arcade expression.
   1. Specify the different point layers. Replace <VariableName1>, <VariableName2>, and <VariableName3> with the point layer names.

var <VariableName1> = FeaturesetByName($datastore, '<VariableName1>')

var <VariableName2> = FeaturesetByName($datastore,'<VariableName2>')

var <VariableName3> = FeaturesetByName($datastore,'<VariableName3>')

2. Return the total number of counts of the different point features intersecting the polygon layer.

return Concatenate([
 `Point1: ${Count(Intersects($feature, Point1))}`,
 `Point2: ${Count(Intersects($feature, Point2))}`,
 `Point3: ${Count(Intersects($feature, Point3))}`,
], TextFormatting.Newline)

var Point1 = FeaturesetByName($datastore, 'Point1')

var Point2 = FeaturesetByName($datastore,'Point2')

var Point3 = FeaturesetByName($datastore,'Point3')

return Concatenate([
 `Point1: ${Count(Intersects($feature, Point1))}`,
 `Point2: ${Count(Intersects($feature, Point2))}`,
 `Point3: ${Count(Intersects($feature, Point3))}`,
], TextFormatting.Newline)

3. Click Done.

7. In the Attribute expressions pane, click the Previous button above the newly created Arcade expression.
8. In the Pop-ups pane, click Fields list > Select fields.
9. Under Expressions, select the newly created Arcade expression and click Done.
