In a system for observing the ground based on various data items measured at one or more observation points by at least one measuring instrument, the measured data items are collected in a collection center, it is determined whether at least one of the measured data items is abnormal based on expert knowledge, a re-measurement instruction is given to the measuring instrument in a case where at least one of the measured data items is abnormal, and the measured data items are edited according to contract conditions for each user to generate measurement data for users in a case where it is determines that the measuring instrument does not malfunction as a result of re-measurement. Thus, the measurement data satisfying users' demands can be generated with good quality and high reliability, based on the measurement data items obtained at one or more observation points.

Method and apparatus for generating measurement data

A plurality of sensing units are buried at suitable intervals in an area of ground or a snow accumulation section to be observed. Each of the sensing units includes a gyro-sensor for, when external force acts on it as a result of the displacement of the ground or the snow accumulation section, sensing impulsive acceleration from the magnitude and direction of the displacement and the inclination of the sensing unit itself, and a transmission section for transmitting the sense data by radio. A base station acquires the sense data transferred from the sensing units, processes the sense data for each measuring point in real time, determines the movement of the ground and/or the snow accumulation section, and judges a state of the ground and/or the snow accumulation section on the basis of the movement.
