Abstract

<pre>A geodetic measurement of shifts and deformations by total station is a well-known and widely used method. There is presented the analysis of the variations over time of the measured values in continuous geodetic monitoring in this paper. There are used measured data from a specific monitoring system of a surface mine in the time period from January 2006 to July 2010 in the analysis.</pre><pre>The aim of the analysis is to describe linear trend and periodic changes in measured data (horizontal direction, zenith angle and slope distance). The main method of the analysis is a linear-harmonic function approximation.</pre>

Summary

Introduction

Special branch of engineering geodesy is a measurement of shifts and deformations, which includes a special case – continuous monitoring. A special case is the continuous monitoring, where the measuring machine records the measured values 24 hours a day, 7 days a week and 365 days in the year. This procedure is used for monitoring of the specific structures or other objects, which creates a large risk of damage to lives and property. There is useful to know in the processing and evaluation of the obtained results, whether the measured value does not change in time in some way other than by the shifts of the target points. It means that the measured values in time grow linearly, drop linearly or their values periodically change
