摘要：Several studies have been carried out aiming the characterization and validation of techniques for performing monitoring survey. Such interest is mainly due to the disasters occurred in the last years, where monitoring survey is one of the tools used to define the actions that need to be carried out to restore the stability and security conditions in the affected region. Taking this into account, in this article a methodology that can be used in the monitoring of unstable areas is presented. In such way, an experiment was accomplished through applying the concept of Reference Line Ratio Method - for corrections of the distances, and with the use of control points to verify with the Total Station the stability of the occupied reference points. It appears that the proposed method is feasible, because when you compare the obtained coordinates with the known ones, the differences were of the order of few millimeters. Therefore, for topographical surveys, the results can be considered satisfactory, since such differences are within the nominal accuracy of the equipment.
