Class Geographic Information Systems

The Geographic Information Systems curricular unit aims to provide students with skills regarding the acquisition, creation, manipulation, storage of geographic data be acquired, and may be applicable to various areas of intervention such as land use, land management, water resources management, infrastructure management, terrain analysis, territory planning, natural and anthropogenic risk management, among others. It is a fundamental curricular unit, which, together with data analysis, will allow students to extract and represent information / geospatial data of great interest to companies.

Not applicable

1. Introduction to GIS: a) Fundamental concepts; b) Geographic information structure; c) History and main fields of application; d) Resources and data/information sources; 2. Software QGIS - structure and main applications; naming rules, forms of organization / management information. 3. GIS data models: Vector, Raster and Tabular. 4. Creation, acquisition and editing data/information; Topological and non-topological models; Geographical databases; 5. Coordinate systems in GIS environment (QGIS); Georeferencing; 6. Tabular data manipulation (selection by attribute, selection by location, join and relate, calculation and statistical analysis indicators); 7. Geoprocessing (Clip, Dissolve, Merge, Buffer, Intersect, Append); 8. GPS - Evolution and current systems. Global positioning system; 9. Raster operations; Interpolation; 10. Surfaces Analysis; Spatial/Matrix algebra; 11. Symbols and representation methods.

The teaching methodology consists of a presentation to the students using PowerPoint, demos and case studies in GIS (QGIS), using data/information available on the web (DGTerritório, IGEOE, APA, etc.) followed by the resolution of practical exercises. The continuous evaluation will have the following components: - A theoretical test, which corresponds to 40 % of the final grade. - A GIS project and respective report, which corresponds to 60 % of the final grade.   In the appeal exam, the evaluation consists of a theoretical test and a GIS project with the same level of difficulty and complexity as the GIS project carried out during the continuous evaluation.
