I want to change from google maps API to Mapbox but some details and routes are missing in KSU campus I uploaded an image of comparison between google maps with lots with details and Mapbox, my question here can I add them manually using Mapbox API (routes and locations) and if I successfully do so, the routing still works perfectly?
Mapbox maps rely on data from OpenStreetMap, a global volunteer project that everyone can contribute to. If you are familiar with this area in the KSU campus, I encourage you to go to openstreetmap.org, create an account, and make improvements directly. You'll have the option to go through an interactive tutorial to get you started. There are more details for advanced editing here as well: https://labs.mapbox.com/mapping. The Mapbox Streets tileset is updated regularly as features are edited or added to the map, which means that if you edit OpenStreetMap, you will eventually see your changes reflected on your Mapbox map.
These changes made to the road network in OSM will also be ingested by the Mapbox Directions API, so that you can use them when routing in your application.
