This is basically due to the recent improvements in GNSS instruments and methodologies that allow high-precision positioning, 24 h availability and semiautomatic data processing. In this paper, GNSS-estimated displacements on a dam structure have been analyzed and compared with pendulum data. This study has been carried out for the Eleonora D\u2019Arborea (Cantoniera) dam, which is in Sardinia. Time series of pendulum and GNSS over a time span of 2.5 years have been aligned so as to be comparable. Analytical models fitting these time series have been estimated and compared. Those models were able to properly fit pendulum data and GNSS data, with standard deviation of residuals smaller than one millimeter. These encouraging results led to the conclusion that GNSS technique can be profitably applied to dam monitoring allowing a denser description, both in space and time, of the dam displacements than the one based on pendulum observations.<\/jats:p>","DOI":"10.3390\/s18030756","type":"journal-article","created":{"date-parts":[[2018,3,2]],"date-time":"2018-03-02T11:53:40Z","timestamp":1519991620000},"page":"756","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Estimating and Comparing Dam Deformation Using Classical and GNSS Techniques"],"prefix":"10.3390","volume":"18","author":[{"given":"Riccardo","family":"Barzaghi","sequence":"first","affiliation":[{"name":"Politecnico di Milano, Department of Civil and Environmental Engineering (DICA)\u2014Geomatics and Geodesy Section, Piazza Leonardo da Vinci 32, 20133 Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8949-7652","authenticated-orcid":false,"given":"Noemi","family":"Cazzaniga","sequence":"additional","affiliation":[{"name":"Politecnico di Milano, Department of Civil and Environmental Engineering (DICA)\u2014Geomatics and Geodesy Section, Piazza Leonardo da Vinci 32, 20133 Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9214-2588","authenticated-orcid":false,"given":"Carlo","family":"De Gaetani","sequence":"additional","affiliation":[{"name":"Politecnico di Milano, Department of Civil and Environmental Engineering (DICA)\u2014Geomatics and Geodesy Section, Piazza Leonardo da Vinci 32, 20133 Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9559-4387","authenticated-orcid":false,"given":"Livio","family":"Pinto","sequence":"additional","affiliation":[{"name":"Politecnico di Milano, Department of Civil and Environmental Engineering (DICA)\u2014Geomatics and Geodesy Section, Piazza Leonardo da Vinci 32, 20133 Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7810-1803","authenticated-orcid":false,"given":"Vincenza","family":"Tornatore","sequence":"additional","affiliation":[{"name":"Politecnico di Milano, Department of Civil and Environmental Engineering (DICA)\u2014Geomatics and Geodesy Section, Piazza Leonardo da Vinci 32, 20133 Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,3,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Scaioni, M., Marsella, M., Crosetto, M., Tornatore, V., and Wang, J.
