Geodatabase Polygons Generalizing When Published from ArcMap 10.1

[ParrBrian]

After publishing a polygon feature class to ArcGIS Online directly from my map document, the polygons are severely generalized in the new service. The feature class in question is a buffer layer and basically the curves are removed and converted to straight lines. However, when I convert the feature class to a shapefile then republish the layer to arcgis online, the curves are preserved.

Does anyone know why ArcGIS is simplifying the curves from the GDB data but not from the shapefile? And if so, how to prevent it from doing so? I'd rather not have to export my geodatabase feature classes to shapefiles, update my map documents, then republish all the data...

Are those GDB features true curves? If so, true curves are not supported in hosted feature services. I'm guessing that the export to shapefile from the GDB converts the true curves to vertices.

Thanks

It must be because they are true curves.

I had this pop up when I first got into AGO.

You can also use the Densify tool instead of going through the export to shapefile process. It will take those true curves and add enough vertices to keep it at that shape. You can also select which objects you want and then use the tool. This way you don't add a bunch of vertices in an object that intentionally should only have 'X' amount like four corners of a building.
