 When integrating several GeoJSON feeds, it may be useful to distinguish the entities of different feeds. The easiest way to do that is by defining an [`entity_namespace`](/docs/configuration/platform_options/#entity-namespace/) for each platform which will prefix each entity ID with the defined value.
