Video 170
In this video I demonstrate how to create and use Attribute Expressions.
To return the area of a polygon use the following in your expression builder:
Floor(Area($feature,'square_kilometers'),2) + "sq km"
Other units available are:
acres | square-feet | hectares | square-kilometers | square-miles | square-nautical-miles | square-meters | square-yards
Attribute Expressions are a good way to add further intelligence to your popups without having to add more fields to the underlying feature service.
