Pre-processing geodetic data of the volcanic area of Teide to monitoring deformations

Abstract

A statistical analysis of data observations in geodetic networks, made before adjustment, provides a means for error control and allows us to ensure a previous accuracy of data. After computing the corrections for systematics effects, distance measurements and horizontal and vertical angles observations are statisticaly analized. Four field campaigns data are analized and a comparison of the results is made in order to detect potential movements in the Caldera of Teide area.
