 ===== About =====
-This feature enables calibrating of an image of a map and placing it over a background map. For example when you go to the ZOO or a park simply take a picture of its detailed plan displayed on a board at the entrance. After that, you can calibrate the photo according to your background map and use it for your further navigation.
