I want to create a content type that I can add to a map view based on nodes. I am using the GMap and Location modules. There doesn't seem to be an obvious way to add users to view based on nodes. So, I want to make a content type, which is a subset of the users and the fields in my user profiles. I know that I can separately have a map view based on my users, but I need to show them all together users, and 3 spatial content types.
My initial thought was just to copy the raw user data from the database and create a content type and populate it from feeds, but this would lead to a lot of duplicate data in the database.
I've created a content type with an entity reference to users. This lets me manually add content with the user name but I don't know how to share fields between the content types and I don't know how to autopopulate the content from the existing user fields.
How do I proceed?
