Mapping but not google maps

[woodyuk]

Hi All,

First post!

I am wondering if there is a 3rd party mapping engine other than MapKit / Google maps. I have not started developing so maybe mapkit will do what i want but was not sure. I am not a developer so will be using someone external.

The main thing is I don’t want to use a Map as in google maps or of a place on this planet.

I want to build a map of an imagery place. However i still want to be able to get directions around it etc. It’s my Virtual Town / city. You can buy mapping engines for windows dev and design your own maps in standard mapping formats - but wondering if anything out there for iPhone that can support that?

Thanks
