摘要：The Geodetic instrumentation of dams are very important to monitore this kind of structure because problems with the dams can represent economical damages, enviromental problems, and the worst situation lost of human lives. The main objectives of this work are to stablish a geodetic network for monitoring the Salto Caxias Dam, develop methodologies for collecting field data, and to present estrategies for data processing. In this work, different survey techniques were applied, such as: triangulation, trilateration, precision geometric levelling and GPS (Global Positioning System) observation, each one with a specific aim inside in the monitoring project. A net with six control points were projected and stablished in the region of the dam, and the point coordinates were obtained at different periods of time. The data collected in the surveying campaigns were processed by using the least squares principles inside the Coordinate Variation Method. There were also applied some statistical tests like Data Snooping Test for the blunders detection. The final purpose in establishing the refered network was to have to have a geodetic rigid reference structure for moniting the time beahavior of the dam.
