I can see with iOS4 you can now tile an image on google maps (Been looking at the TileMap example from apple). This is great as this is what I want to do, but from what I can see I need to know the GEO reference of the image so I can raster the images with the appropriate zoom levels, etc. What I have is an artist image, which is a map of a specific area and I want to overlay this image on google maps.
Am I missing something here, but can this be done with a none standard map and having different zoom levels?
The main reason why I need to use google maps is because of the GPS functionality, so the user will know where they currently are on the map.
