Abstract: A method for obtaining a map comprises: capturing a map image from a physical map, obtaining a plurality of geographical coordinates corresponding to a plurality of reference points from one of the physical map and the map image, calculating a corresponding geographical coordinate of each pixel in the map image, and embedding a relationship between each pixel and its corresponding geographical coordinate into the map image.

Abstract: A map marking method comprises capturing a map image from a physical map, capturing a plurality of reference coordinates corresponding to the physical map, obtaining a positioning coordinate from the global positioning system, calculating a positioning site on the physical map corresponding to the positioning coordinate according to the plurality of reference coordinates, the map image, and the positioning coordinate, and marking the positioning site on the physical map. As such, a user may arbitrarily mark his/her own position on a physical map with his/her positioning device utilizing the above mentioned method, and may explore the world more conveniently.
