The teaching methodology consists, first, in lectures by master classes in which student participation is encouraged.

Moreover, in practical classes based on the management of digital photogrammetric systems and teaching by developing real projects, specific software and practical exercises.

Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support

The evaluation system is intended to verify that the students have acquired the expected learning outcomes in the subject. This evaluation must demonstrate that:

1) They have acquired the necessary knowledge of the photogrammetric and topographic instrumentation and methods for the application of methods and tools of digital photogrammetry and other technologies for direct orientation sensors and the generation of digital elevation models and orthophotos.

2) They have acquired the knowledge and skills necessary to apply least squares methods in the field of geomatics observations.

The evaluation will consist of three parts: attendance, theory + problems and practical exercises.

The evaluation of the first part will be performed by controlling asisitencia both theoretical and practical classes.

The evaluation of theory+problems will be done through a written test.

Finally, the evaluation of the practical part is based on the delivery of the relevant reports to practices implemented, as well as conducting survey on the relevant subject.

The final grade will be the result of performing a weighted average of the ratings of the three parts (attendance, theory+problems, practical exercises), with their weights of 0.1, 0.65 and 0.25 respectively. For this average is made will need to have achieved a minimum score of 5 points on each of the parties.

According the defined competences and provided results, and the evaluation applied methodologies, it is possible to establish the following correspondence:

Attendance: R1, R2, R3 / CE25, CE26, CT6

Theory+Problems: R1, R2, R3 / CE25, CE26

Practice: R1, R2, R3 / CE25, CE26, CT2, CT4, CT6
