Objectives

Obtain general knowledge of photogrammetryc concepts, with emphasis on digital aerial photography, and focused on topographic mapping and geographical information production.

Learning outcomes and competences

The student should have the fundamental theoretical concepts, together with competences for carrying projects of aerial triangulation, orthorectification and restitution of vector data for topographic mapping.

Working method

Presencial

Teaching methods and learning activities

Classes will have an expository component, with projection of slides and deduction of mathematical formalisms on the board, accompanied by practical demonstrations using specific photogrammetric software.

There will also be a component for solving photogrammetric problems, using a spreadsheet or programming. A digital photogrammetry project using photogrammetric stations (Trimble Inpho) is developed. The Agisoft Photoscan software is also used, with the necessary adaptations for processing conventional aerial images, as an alternative to drone images.. The exercises are started in class, but the largest component of time will consist of student work, outside of contact hours. Students will present two reports of their work, one in the middle of the semester and another at the end.

At the beginning of the semester there will be a study visit to the company Infoportugal, at the Maia aerodrome, to observe an aerial camera mounted on an airplane. At the end of the course, there will be a one-day field trip to the Army's Geographical Institute and to the Municípia company, in Lisbon.

Type of Assessment: Distributed assessment with final exam.

Assessment formula:

Final classification = 50% Reports + 50% Written exam.

The two classifications must be greater than 8 points.

There may be a discussion of the reports (10 minutes per student).

Eligibility for exams

Presence in 75% of the lectures.
Presentation of reports of the the projects carried out in the practical work along the semester.

Calculation formula of final grade

Final classification = 50% report + 50% written exam. Both classifications can't be less than 8 (in 20).

There may be a discussion of the reports (10 minutes per student).

Examinations or Special Assignments

Internship work/project

Special assessment (TE, DA, ...)

Classification improvement

Classification can only be improved in the final exam component.
