The Maps SDK by CartoDB includes a routing API that enables users to find the fastest path between any number of points and get route and turn instructions. The routing API works on both online and offline modes, with similar APIs for all platforms including iOS, Android, and Xamarin. Offline routing requires pre-downloading map packages, which can be downloaded by selecting a specific data source and package ID. This process involves downloading larger files compared to the original map packages, such as 117MB for New York's US-NY-routing data package. The developer guide is available at https://developer.nutiteq.com/guides/routing, and code samples are provided for iOS, Android, and Xamarin platforms.
