Abstract

This work aims to establish a methodology to compare the displacements are obtained by performing geodetic auscultations by observable angular (theodolite) and electronic distancemeter (EDM), all with the object of choice "a priori" the best instruments to carry out such work. To justify the contrast it have been proposed the methodology and instruments used in the resolution of auscultation of a dam called "La Cohilla", located in Cantabria (Spain). This one have been observed by classical methods, angles and distances, in two consecutive seasons. First of all, the displacements of a series of targets with both observables are obtained. After that, it is proposed a statistical procedure to validate the results obtained with both observable and thus be able to make the right decision about the appropriate choice of the observable and therefore what instrumental must be employed in geodesic auscultations.
