JMap Server may use a vector spatial data source that comes from another JMap Server instance. To enable this, you must start by configuring a connection towards the other JMap Server. Refer to [JMap Server to JMap Server Connections](https://docs-jmapserver-lima.k2geospatial.com/e/administrator/jmap-server-administrator-manual/resources-jmap-server-to-jmap-server-connections) for more information.
