摘要：The control instrumentation of dams are very important to monitore this structure because problems with the dams can represent economical damages, enviromental problems in the worst lost of human lives. The main objective of this work is to stablish a geodetic network for monitoring the Salto Caxias Dam, develop methodologies collect data in the field and present away to process the data. In this work different techniques of survey were applied, such as: triangulations, trilaterations, precision geometric levelling and GPS (Global Positioning System) observation, each one with a specific aim inside in the monitoring project. A net with four control points were projected and stablished in the region of the dam, and the point coordinates were defined in different periods of time. The data collected in the surveying campaigns were processing using the least squares principles using the Coordinate Variation Method and it were also applied Data Snooping Test for the detection of blunders, considering that this network will be the reference to monitore the dam.
