Offline map API for mobile development

Question

I am actually developing an iOS/Android application containing a map showing some places (like nearby places). I want to introduce a concept of offline map, in other words I want that the user can, when he is online, download the offline map (with the same informations contained on the online map).

The goal of this, is not having the map of the whole world or a continent, is just a city (New York for example) showing street's names and I can add annotations on it.

I don't really know from where to start to make this.

If someone has an idea, or already tried a good solution please let me know about it.

Thanks in advance.

Answer 1

There are some non-Google tools which do offline mapping. I would suggest to take a look to Nutiteq SDK, if you use it with OpenStreetMap (including MapBox) then it is free, and it has all the features what Google has, including tilted/rotated map, and some extra features like 3D buildings and freedom to select any map source, including offline maps.
