My work team is planning to work with data from the ArcGIS Collector app in excel (exported from ArcGIS Online as a .CSV) and require the area of each polygon feature for later analysis. When our polygon feature layer is published as a service from ArcMap, the Shape_Area field appears to have been lost as an attribute and is not available to be displayed in the popup or table. I took a look at the layer in the REST services directory and it looks like the field was completely lost. Is there some way I can make sure the Shape_Area field is packaged with all the other custom fields in the hosted service?
I am still very new to ArcGIS programs (about a month in) – sorry if my terminology is off! Let me know if this is unclear and I can try and rephrase!
