@Moi_Nccncc - There isn't a gallery of templated or example GeoEvent Services currently but this is something the Real-Time team can look into offering on the GeoEvent Server Gallery if there's enough interest from the broader community. I suggest posting this idea to our Ideas page if you haven't already!
In the short term, I would recommend checking out some of the various recorded GeoEvent Server sessions from past conferences. Our "Applying Real-Time Analytics" line of sessions usually delve into GeoEvent Service design and demonstrations.
