Feature Z

Since version: 1.5

In the Feature Z profile, expressions can be written to calculate z values for features in a 3D scene or to define the draw order for sorting features in a 2D map view. This is useful in datasets where z information is stored in an attribute instead of the feature's geometry. You can use this profile to return the attribute in lieu of a missing z value. Expressions in this profile must return a Number representing the Z coordinate of the geometry.

Context

This profile was created for use in the following products:

• ArcGIS Maps SDK for JavaScript
• ArcGIS Pro
• ArcGIS Maps SDKs for Native Apps

Spatial reference

The spatial reference of the map in which $feature is rendered determines the spatial reference of the expression's execution context.

Example

The following example gets the geometry of the feature, and adds the value of the HEIGHT attribute, to create an adjusted height value.

var adjustedHeight = Geometry($feature).z + $feature.HEIGHT;
return adjustedHeight;
