How to use own map database to display map on a website and use that map to find route and do other stuff ?
That is an absolutely massive task, I'm not sure I understand your question correctly... You've tagged this with Javascript
, Web-development
and map
- so presumably you want to know how to implement a front-end that renders a map to a web page, and then performs custom pathfinding and other logic. Surely I'm misunderstanding you! :D
