Abstract
AbstractThe paper presents a case study on the application of Geomatics to terrain’s deformation monitoring. Within the EU H2020 LiquefACT project, the Laboratory of Geomatics of the University of Pavia (Italy) was appointed to quantify the subsidence suffered by the terrain due to some trials conducted in the test site of Pieve di Cento, Northern Italy. Geomatics has long been used for deformation monitoring, but present paper deals with two peculiar elements: the constraints given by the test field, its layout, the allowed and forbidden actions, that forced the surveyors to elaborate an unconventional surveying design, and the use of a state-of-the-art instrument, the Trimble SX10. It mainly is a high-level topographic total station; being robotized, it has interesting laser scanning capabilities. In the paper, the survey design will be illustrated and discussed, and a selection of the obtained results will be presented. They highlight how much geomatics can be flexible and adaptable and, at the same time, precise and accurate.
