In our enterprise we always used ArgGis. Now we are required to move from heavy apps to thin WPF-Prism clients. As I understand, with the coming deprecation of ArgGis Objects, the ArcGis desktop will be the only way to create new content.
Our application requires to create new content (such layers) from Client's side and in a Service-Based fashion.
After analysis we found any ArgGis-Objects-Server-Desktop combination (client and server side) unacceptably expensive.
So, we have decided to move to an Open Source Solution.
I would like to know if you could recommend me some options for an OpenSource (or paid) GIS engine consumable by custom mashups and that exposes full content creation via web services (not like that ArcDesktop stuff).
Thank you very much!
