Hello, salmanmemon. You are far in advance of me in this area. I have no experience coding, so I can't give you any advice on these topics. Good luck!

hi i'm working on project of GPS Mapping research is running i have 2 options
make a real time application for my map
or just make a update map and send it to all GPS receivers vendors and google also.

2 option easy but i want go with 1 one but i don't know how to make real time application for gps. is there any gps real time navigation software available in the market in which we can extend the map in our own and extend application then send to end users
