Storing Indoor Room Map Information into Arduino

Hello!

I am working on a navigational belt project which directs visually impaired users to find their way around a small room. May I know if anyone has experience in storing indoor map information, maybe in terms of coordinates and also the direction in which the user is facing into the Arduino Microcontroller? Would appreciate any help to get started in this direction!

Thank you!

You will likely need to store the map data outside of the Arduino due its limited built-in memory. An SD card is often used and easy to integrate with an Arduino for this type of projects.
