Where to start with the map application

I am trying to create a new application that will allow the user to see his current location on a user map (office, university compass, etc.). but actually I have a couple of questions in my opinion (I have not developed this kind of application yet). I am wondering:

  • How can I draw my own maps, which is the best option for this? Is there some format that I need to take care of, are there any specifications about this?
  • As soon as I have a custom map. How can I do this to map the global coordinate system to local positions?
  • What are the tricks associated with map scaling? just different levels with more or less information and do these layer changes per user require?
  • If you want to mark some specific points above the map, for example, a cafeteria, a boss’s office, etc., how can I do this?

Sorry if there are too many generics and dumb ones in my questions, but I really need some tips on this topic, because I don’t know how to create such an application as best as possible. and we don’t want to reinvent the wheel.

I will be grateful for any help you can provide me with this application.

There are several approaches to creating a map application. Which one you use depends on the set of features that you want to support, and the degree of control that you want to maintain over the product.
