Calculating Geometry in ArcGIS Online.

[MichaelTorbett1]

Hello, in my organization we have developed an app using the web app builder that allows users to draw polygons for forest stand types. However, it cannot calculate geometry in the attribute table. Specifically area in acres. This is for ArcGIS Online.  Has anyone figured out how to do this or know of a sample code that I can work off of?

Thanks, Michael

Michael,

you could modify the code to, calculate the area in acres and then write it into the attribute table.

Here is a nice example on how to do the first part: ArcGIS API for JavaScript Sandbox
