Is this possible with GPS? If yes, How?

Happy New Year to all the Community!!!

Please, I want to know if this is possible to achieve in Android.

I work at a University that, of course, has a lot of buildings and each of them has his own name.

What I want to do, is an Android app that somehow (maybe detecting the GPS coordinates of the buildings), shows on screen the pictures, name of building, name of the dean of a career and his office number if inside a specific building, etc.

Of course, I don't want the user to press a button each time he/she is in a building. I want him/her to be able to walk across the University with the app opened, and the app itself change the information automatically depending on the building where the user is.

I hope someone undestands me, and can help me on a guide on how to achieve this if possible.

Thanks a lot!

mm, did you check that GPS work under roof?

and also you need to do so an accuracy less than 5 meters, that will drain your battery quick.

but if you are sure that under roof of theses building the gps work (not the google locator) and it meet the accuracy all is OK.

Thanks Fernando!

Didn't think about the under roof problem...

I'll check if the GPS works and let you know.
