Objectives

At the end of the semester, students are expected to be able to:

- Understand how spatial data should be structured.

- Understand the different acquisition methods of geographical data (2D and 3D), organize and construct the information from the acquisition phase to the treatment in the office.

- Extract information from terrain models to generate hypsometric maps, slope, aspect, shaded relief, intervisibility, and calculation of volumes and profiles.

- Demonstrate skills and knowledge related to the acquisition, manipulation and analysis of three-dimensional information, and apply this knowledge in various scientific contexts and areas.

- To structure and graphically represent three-dimensional information, articulating it with the knowledge of cartography regarding its applicability in the various areas of Territorial Planning.

Learning outcomes and competences

UC develops the fundamental concepts for creating and manipulating data in a GIS environment regardless of source. The works are based on exploring 2D and 3D spatial data acquisition and editing methods that allow information organisation in geographic databases. Besides implying practical knowledge in manipulating GIS software, this process requires a common theoretical knowledge of methods of acquisition, topological rules and legislation. In addition, the UC also aims to develop the student's knowledge and skills that allow the use of three-dimensional analysis tools applied to treat geographical information, articulating their representation with previously acquired cartography knowledge. They must therefore take a critical stance on the results, recognizing the importance of the treatment and analysis of three-dimensional information in various scientific areas.

Teaching methods and learning activities

The applied teaching-learning methods combine theoretical presentations, the accomplishment of exercises in GIS and the analysis/discussion of concrete cases to allow the students to apprehend and fulfil the previously mentioned competencies. The content exposition is based on the presentation of documents prepared in PowerPoint and made available in Moodle, where all the essential information necessary for preparing the exercises is also available. These are the main component of the classes, always interspersed with the theoretical aspects, so that the students perceive the principles of operation of the UC subjects. In the practical component, group work (2 or 3 students) with the accompaniment of the teachers.

The evaluation is distributed without the final exam: practical work (in groups of 2 students) - 60%; Individual test - 40%.
