How would you route routes between points on the map? What are the missing parts?

Question

On iOS 6, the Maps app disables Google Maps. The Google Maps SDK Terms state that if you specify routes with your service, you must show them on your map. Since this will not happen anymore, I need to explore other options in order to get the routes and display the routes on the map.

I found that MapQuest and Nokia offer an API for providing routing and routing services.

• MapQuest - http://open.mapquestapi.com/directions/
• Nokia - http://api.maps.nokia.com/en/apireference/2.2.0/symbols/nokia.maps.routing.html

I also see that OpenStreetMap has a list of online routing services with different support levels for different locations, and some of them are in a preliminary version state.

I did not do much with routing before I wanted to find a mapping tutorial that covers the basics. The big question I have is curves in the routes. I only know the coordinates for the maps. I do not know how to determine a route by a curve, if this does not mean using a large number of coordinates to draw a curve. I would appreciate some explanation of what to do for the curves. Ideal for famous routes such as roads, as well as sidewalks and footpaths, would be ideal. A basic guide to laying directions along known routes would be most useful.

All help is appreciated. I know that many developers who prepared applications for iOS 6 will study the services for routes and routes, and I hope that the information collected with this question will be the starting point for them.

Answer 1

The MapQuest iOS Maps API includes routing features. Perhaps worth a look?

MapQuest also offers the JavaScript API (which supports mobile devices) and the Mobile Flash API (using the Flex SDK to create native apps for iOS and Android), which are essentially wrappers for the core MapQuest Web Services , including the Directions service you mentioned .

Hope this will be helpful!
