Calculating polygon area

Hi @regulusdeneb Is _area an attribute on the output schema or does the ExpressionEvaluator set a new attribute with the area? The Data Inspector is only showing the output of the AttributeCreator which is before the AreaCalculator.

I changed _result to AREAHA in ExperssionEvaluator and AttributeRounder and the result still does not get written. I should have mentioned this earlier (sorry).. I have a dialog box pop up when I run it that says, "...some features were read that did not match a reader feature type in the workspace." Is this what is causing the problem?

I expose kml_description and kml_name in the reader, then change their names in AttributeCreator, then reproject to UTM NAD83. Thank you..

@regulusdeneb I don't think the pop-up is the problem. Can you send your workspace to https://www.safe.com/support/report-a-problem/ ? Thanks

Hi @regulusdeneb

I see there is a red arrow on the input of the Writer.

This would suggest that some of the writer attributes are not picking up an input. If you click on the drop down arrow you will be able to see which ones are missing and manually connect them to the right output from the ExpressionEvaluator.

Thank you both for your help to this point. I have uploaded the workspace to Safe at @DanAtSafe's request. Btw, I managed to hook up kml_descri in the writer with kml_description in AttributeRounder and made kml_descri's arrow green. But I still get "Unexpected input" to pop up when I run it.

Thank you again for the help. I ran this after almost a month away from it and it works now despite that I did not change anything. I guess I just needed to close FME and reboot maybe.
