I have integrated offline maps into my project with the help of route-me sample app (https://github.com/route-me/route-me). But my client wants to show topographical type of map as the open street map. I have searched over the internet, couldn't find any helpful resources.
Do you know any resources I should follow to implement this feature?
Should I have to use another way of implement the Open Street Maps in order to get the topographic type of map?
