Augmented Reality Geo location App

This will be an iPhone app that uses augmented reality and Geo location features. I am looking to set it up to put in multiple locations that people can use the app to see where certain buildings are using their iPhone. This will be used for a college campus. Instead of using paper maps to find buildings, people will use this app and see exactly where everything is located and not get lost. The building locations will be their longitude and latitude. While using the app it will show the name of the building in a small box on the screen. I would like there to be a radar too in the top right of the screen that would show where other locations are located within a certain distance. Please look at the attachment picture of what I would like it to look like. This will be a very simple and basic app that I would like to test out and then further develop after testing it out.
