Objectives

Learning outcomes and competences

The students are expected to:
a) understand the gravity field of the Earth and the geoid determination;
b) understand how classical/modern geodetic networks are established, the relevant geodetic observations, and network computation/adjustment;
c) perform make computations on spherical and ellipsoidal Earth models;
d) understand the various height systems and how to apply them;
e) be able to apply this knowledge in other curricular units of the master (e.g., Positioning and Satellite Navigation).

Teaching methods and learning activities

Theoretical classes are mainly based on PowerPoint presentations and available on the site of the course. Whenever possible, an updated copy of the UC Notes, in PDF format, is also provided to students.
In the tutorials, an extensive set of exercises covering all course sections, aiming at the application and consolidation of the knowledge acquired in the theoretical classes, is solved (software for numeric computation and data analysis, e.g., MATLAB, can be used).

Eligibility for exams

The attendance in the tutorial classes is compulsory according to the University of Porto rules.

Calculation formula of final grade

The assessment is based on the final written exam (FE) and the practical/project work report (PR), proposed and carried out throughout the semester.

The final grade (FG) will be equal to FG=0.7*FE + 0.3*PR.

The final classification of the UC is the FG if ≥9.5 values. The classification of each component must be ≥ 8 on a 0-20 scale.

Special assessment (TE, DA, ...)

The University of Porto rules are obeyed.
