The teaching methodology is based on the one hand, a large group classes where exhibitions of the theoretical concepts of the subject and problem solving and case are made. These classes follow a master class scheme in which student participation is encouraged. Also, practical classes in small groups taught at the Laboratory of Digital Photogrammetry for handling specific equipment (photogrammetric scanners, digital photogrammetric stations and other specific software) are performed.

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 skills provided for the subject, reaching the intended learning outcomes. This evaluation verified that:

• They have acquired the necessary knowledge of the implementation and photogrammetric and topographic methods for the application of methods and instruments in Digital Photogrammetry, including airborne and spaceborne image orientation, and the generation of digital elevation models and orthoimages .
• They have acquired the knowledge and skills necessary to apply the least squares methods in the field of geomatics observations.

The evaluation system consists of two components:

• Theoretical knowledge and solving problems
• Execution of practical work.

The assessment related theoretical knowledge and problem solving would be done through a written test, which is divided into two parts:

• Theoretical knowledge will be assessed by different questions on the subject taught (the questions may have different configurations depending on the items to evaluate, from short questions to topics to be developed).
• Problem resolution to be developed by using a computer system (spreadsheet).

It is considered that this part is overcome when at least 50% of the maximum score set is obtained for each of them.

The evaluation regarding the practical knowledge (execution of practical works) will be based on the presentation and defense of the works carried out by the students in the practical classes. Those people who do not pass this evaluation may opt for a global competency test.

The final grade will result from performing a weighted average of the rating of the three parties (attendance and participation, theoretical knowledge and problem solving, execution of practical work) where his weights of 0.70 and 0.30, respectively. For this average is done will require the student has reached at least 50% of the maximum rating in the assessment of theoretical knowledge and problem solving, and the accounts for the implementation of practical work.

According to the description of competencies and results to be achieved and evaluation methodologies applied the following correspondence is established:

• Theoretical knowledge and problem solving: R1, R2, R3 / CE25, CE26
• Execution of practical work: R1, R2, R3 / CB2, CB4, CT1, CT2, CT4, CT6, CE24, CE25, CE26
