Abstract: A method for measuring a location of a user terminal, using a magnetic field includes receiving information on a map of the magnetic field; acquiring a first measured value from a magnetic field sensor provided in the user terminal; acquiring a second measured value from another sensor provided in the user terminal and distinguished from the magnetic field sensor; and measuring a location of the user terminal based on the information on the map of the magnetic field, the first measured value and the second measured value.
Abstract: A method for constructing a map of a magnetic field includes acquiring the map information including the information on the internal or external structure of the building; measuring the information on the magnetic field, using the measurer's electronic device; and associating the information on the magnetic field with the map information based on the schedule information, wherein the schedule information is generated based on the structure information or a command made by the measurer.
