I am trying to publish a feature service that includes the geometry fields, SHAPE_Length for example, with no luck so far. Am I missing something here or is this not possible? Thank you in advance!
Looks like the Shape_Length (and other geometry fields) are not published with a feature service...work around would be adding a new field to the attribute table in ArcMap and store the length in that field which will then be accessible in ArcGIS Online.
SHAPE.Area field in a feature service
A little more information regarding the issue would be helpful...how are you publishing the data (from ArcMap, Shapefile, CSV, ect...)? It is possible the field is simply turned off for viewing in the pop-up and/or table.
I am publishing the data from ArcMap. It is a feature class in a FGDB. The SHAPE_Length field is turned on in ArcMap when published to ArcGIS Online, but is not available (missing) from the pop-up configuration on ArcGIS Online.
