Description
The present invention relates to a terrain change monitoring system for monitoring, detecting, and predicting a change in a terrain due to subsidence or the like, so that measures necessary for prevention of a disaster can be taken in advance.
To do this, a level survey can be performed. In the case of the level survey, the relative height of the other points is measured based on each point, and the entire terrain is measured.
In the case of a terrain change occurring in a wide area, it is common that the ground surface of a certain area forms a gentle slope and sinks concavely or convexly. Therefore, the change of the inclination angle of each point is measured, Or a method of monitoring the elevated state.
In the conventional leveling, a leveling method is generally used. In the case of the leveling, the relative height of other points is measured based on each point to measure the overall terrain. However, measurement is time-consuming and costly, and it is not sufficient to monitor real-time monitoring of the overall terrain changes that occur in a large area.
In addition, the general level measurement basically measures the height of each point of the terrain, builds basic data, measures the height of each point again, and calculates the height difference between the basic data and the newly measured data. It needs to be reduced.
On the other hand, Registration No. 766070 (Oct. 4, 2007) regarding a terrain change monitoring system using GPS is disclosed,
