摘要：The background of this research is in the easy measurement of the difference of elevation of the surface of the earth in the developing countries. The leveling is being measured by generally using the level and GPS now. However, there are times when the measured range is wide-ranging and in the urban area and the mountain where the electric wave does not reach easily, are difficult in the level and GPS. Then, if the difference of elevation can be measured by installing the inertia l device in the vehicle, the leveling of the large area easily becomes possible. Because a inexpensive gyro had the fault with low accuracy in a past inertial survey, the method of not using the gyro was examined. Then, this study developed the method of obtaining the difference of elevation by using the accelerometer and the vehicle speed sensor
