This research aims at developing an electronic culture atlas using smart phones as a way to share the research results of Mind Humanities. An electronic atlas offers the web service of a great deal of information without the limitation of paper, which is different from the existing paper maps. When the concept of culture is added to an electronic atlas, it becomes an electronic culture atlas. To create an application program using smartphones, their various features should be understood and the development method to maximize them is necessary. Accordingly, in this paper, what needs to be taken into consideration for the service based on smartphones and the characteristics of smartphones to be considered in the development process were examined.

Research on indoor location tracking technology using smart phone is actively being carried out. Especially, in order to display the movement path of the smartphone on the map, the azimuth angle should be estimated by using the geomagnetic sensor built in most smart phones. Due to the distortion of the magnetic field due to the surrounding steel structure and the inclination of the smartphone, the estimation error of azimuthal angle may be occurred. In this paper, we propose a correction method of the geomagnetic sensor at the stationary state and a correction method for the inclination of the smartphone. We also propose a method to correct the azimuth error due to the difference between the magnetic north and the grid north.
