Well it is an actual island, available on any world map including Google's. Though, this map has more details and it's designed to help tourists find out what is to be seen around the island. It also contains all businesses and local services, listed directly by the KFZ Org.
I'm wondering along the same path. I can imagine why you wouldn't want to use google as your main source, but any reason you didn't use openstreetmaps apis?
As for the map, I'm not responsible for that matter; but AFAIK it was specifically asked! Besides, every single detail is carefully highlighted manually, so we could say it's more precise than Google Maps (plus the sanctions situation). and as I mentioned in a replay to another comment, KFZ Org. provides local business information; so it basically contains (should contain) every single business and public service available on the island.

What is the idea behind the Kish free zone? Is the idea to experiment with alternative economic models like you sometimes see in china for specified regions? Same government, alternative laws?
Unfortunately, I'm not aware of the technical details of the back-end, as I was only responsible for the front-end application development.
