How do I remove the map after looking at it so I can continue with the Game?

When you open the phone to look at the map there should be an X in the top right corner to close it again. If you don't see this the just try taping around th edge of the screen outside the map display. If it doesn't close then there may be a bug with your game or perhaps it doesn't work well on the resolution of your device. You can try restarting the app and then using the settings menu to contact game support to report it.
