Question

Navigation in space

Good day gentlemen. There is a question about the types of implementation of interactive maps. The task is to implement a map that will be used to navigate inside the building (university). Position data will be generated from QR codes. Actually the question is: "Which direction (technology stack) to take to implement this project" .
Thank you.
