WFS (Web Feature Service) is a standard defined by ISO (the International Organization for Standardization). It describes a method whereby applications can access geographic feature data and their associated attribute data regardless of the format of the underlying database. Bentley Map support for WFS is currently read-only.

Because the WFS client support is read-only, there is little direct interaction with the WFS server itself. When connecting to the service, the client discovers the version supported by the server and the features available. The user can query the features using the standard Bentley Map query tools. Features queried are transformed into the geographic coordinate system of the active design file.

Even though the WFS service is read-only, features still must be locked to be edited with Bentley Map. Any edits cannot be posted back to WFS, rather they become part of the current DGN.
