How to Build Map app Navigation using MapBox API?
问题 I want to make map app for blind users in KSU campus using Mapbox API that position your location and gives you the routing to your destination turn by turn and tell you about the places in your way by voice. I want it to work in offline mode, also the user can search for his/her destination using keywords or by suggestions based on categories such as restaurants, faculties, etc. Do I need database, can you give me tips and summary on the things I will do like you can say conceptual overview?
