Abstract:
A method of measuring an altitude in a portable terminal is provided. The method includes receiving a reference altitude from an information providing device fixed and installed at a certain point, measuring a current atmospheric pressure of the certain point, calculating an altitude of the certain position using the measured current atmospheric pressure and a reference atmospheric pressure, and storing a difference between the reference altitude and the calculated altitude of the certain point as an altitude error.
