Slope Monitoring System

Abstract

PROBLEM TO BE SOLVED: To make graspable precisely the state of a slope by reducing dispersion in slope displacement data and reducing missing data. SOLUTION: A GPS transmitter which is a reference point is arranged on a position outside the slope, and one or more GPS transmitters are arranged on positions in the slope. A monitoring center acquires reference point position information for showing the position of the reference point GPS transmitter and position information for showing the positions of the GPS transmitters arranged on the slope, and acquires slope displacement data by determining the slope displacement based on the reference point position information and the position information. The monitoring center evaluates the slope displacement data corresponding to an evaluation index specified beforehand, and displays the slope displacement data, classified by color, corresponding to the evaluation result. In the monitoring center, preference of the slope displacement data is evaluated based on the evaluation index, and the slope displacement data determined not to be preferential are taken as missing slope displacement data, and the missing slope displacement data are interpolated based on the preferential slope displacement data determined to be preferential.
