I am trying to build Anylogic agent model with Countries, Cities and Airports. I've created Countries population in Main agent, Cities population in every Country agent, Airports population in every City agent. Airport agents have coordinated and should be placed on GIS map, located in the Main agent.
However, they are not displaying now, and the only population that I can place on the Main GIS map is Countries.
How can I place Airports nested agents on Main GIS map, without creating new population of airports directly in Main?
