Learning physical geodesy. Application case to geoid undulation computation

Abstract

The present article shows a novel approach for the acquisition of competences related to physical geodesy in the Bachelor's Degree in Geomatics using virtual materials to promote the autonomous learning and support it during exceptional periods of confinement, like the Covid-19 pandemic. More specifically, the article is focused in the geoid undulation determination, which is a critical issue in hydraulic works, land subsidence, and civil projects. So, this concept has to be learned in the Bachelor's Degree in Geomatics for the proper acquisition of competences. The approach is aimed to three-dimensional fitting techniques and statistical analysis to improve the comprehension and interpretation of the different local geoid models from the same set of field measurements, and therefore the conclusions and analysis derived from them for the subsequent Geomatic practical works. The current contribution is originated from the virtual laboratories’ paradigm, as it is proposed the use of virtual materials for the acquisition and evaluation of competences and skills in an asynchronous way, that can be use not only for and e-learning or b-learning programs, but also as support for traditional face to face programs. The present contribution will help the students to contextualize the theoretical knowledge, so better understand the challenges they will face in the working market as future professionals.
