Is it possible to dynamically update maps?

Question

satellite navigation

Can you please tell me if it is possible to dynamically update the contents of the map in the application using GPS coordinates? Suppose there is an application that receives coordinates from GPS, transmits them to the server, and receives back information about what objects may be near these coordinates and displays them on the map.
If this is possible, what maps are best to use, well, or a navigation program that allows you to do this?

Answer 1

Here, there is an application that receives GPS coordinates, transmits them to the server, and gets back what objects are possible next to these coordinates and draws them on the current map!

Of course it's possible.
Google, Yandex, 2GIS, depends on the country and what kind of objects, because all these services are provided by a server with a database of objects that can return them according to certain criteria, but you can create your own database if necessary.
