To teach the basics of map projections and their implication in map production and geographical information storage. To describe the national map series in Portugal, both topographical and thematic.
Knowledge of the different map projections and capability of converting coordiniates by own programming and by specific software.
Capability to analyse maps of topographic content, as well as thematic.
To know the portuguese map series and their map projection systems.
1. Introduction.
History of Cartography and revision basic concepts involved in Cartography.
2. Content and use of maps.
2.1. Example of topographic and thematic maps.
2.2. Analysis of map content and map reading.
2.3. Portuguese national cartographic series.
3. Map projections.
3.1. Aspect, classification and names of map projections.
3.2. Mathematical concepts involved in map projections.
3.3. Derivations of cylindrical projections of the sphere: a) Equidistant (Platté-Carré), b) Mercator, c) cylindrical equal-area.
3.4. Generalization to the ellipsoid.
3.5. Gauss projection. Principles for its derivation.
3.6. Modification of a map projection.
3.7. UTM system.
3.8. Reference to other projections (Lambert conformal conic, polar stereographic, Bonne).
4. Portuguese map projections.
4.1. Old projections: Bessel-Bonne, Hayford Gauss (datum Lisboa and datum 73)
4.2. Current official map projection (PT-TM06/ETRS89).
4.3. Identification of map projections by EPSG codes.
Theoretical lectures (2h/week) with topics presented with powerpoint slides, deductions in the blackboard, and demonstrations in specific software.
Practical lectures (2h/week) of map analysis and numerical calculations of map projections (Excel/Matlab, PROJ.4, QGIS)
Distributed assessment with final exam. Final mark is the average of the exam classification and the result of mini-tests done in the practical lectures along the semester.

Two mini-tests (MT) will be done during the practical lectures.
Final classification = 50% MT + 50% exam.
