How to work with 'geometry' object in new AGOL 'Arcade' expression language

Anonymous User

Has anyone got any info or documentation on how to work with a geometry object using the new 'Arcade' expression language just introduced to ArcGIS Online?

e.g. at the simplest level, how would you access the area of a polygon and return that, perhaps converted to a particular measurement unit?

Cheer,

-Paul

aaaahhh good point. So the original question remains....

because in the blog example, it assumes that the Area field is already populated somehow. Whereas, using the actual geometry object would allow the label to dynamically update on the fly as the geometry changes.

I'll leave the question open then in case someone else knows. I've looked over the Arcade developer site but it's doesn't seem to go into detail around the geometry object properties and methods...

This example does not actually use the Geometry object though, it expects a field called "Area".

thanks Andrew - I hadn't seen that particular blog post.

There is an example here:

Round($feature.Area * 0.000247105, 3) + " Acres"
