The class illustrates the characteristics of digital cartography, where to find it and how to display, query, integrate it with current geo-services available via the web and analyze it using GIS (Geographic Information System) free and open source software. The approach is very operational, with computer exercises dedicated to the natural (terrestrial and marine) and built environment, in different interdisciplinary areas of study.
The use of free and open source geographic software (GFOSS) and the expertise acquired in the management of geographic data ensure that the teaching contributes to the following Sustainable Development Goals of the UN 2030 Agenda:
Goal 4: Provide quality, equitable and inclusive education and learning opportunities for all
Goal 10: Reduce inequality within and between nations
Goal 15: Protect, restore and promote sustainable use of the Earth's ecosystem
The class provides operational GIS (Geographic Information System) tools for search, visualize, query, managet and simply analyze digital cartography and geo-referenced data. It allows to address concrete applications in the different fields of study of the urban and natural (terrestrial and marine) environments.
At the end of the class, the students will have acquired the theoretical and practical techniques of management and analysis of geo-referenced spatial data.
Students will then be able to:
use GIS software, with particular reference to free and open source software (in accordance with the directive of the Minister for Innovation and Technology of December 19, 2003 that encourages their use), for the resolution of concrete and interdisciplinary applications in different areas of study: land and environmental management, decision support, urban planning, geotechnic, hydrology, hydraulics and transport, as well as management of surveys on digital cartographic support.
find, visualize, process, integrate and analyze cartographic data from various sources (municipal, regional, national cartographic portals, ...)
identify the most suitable cartographic data and the necessary elaborations to obtain the expected result
evaluate the obtained obtained as a function of the metric resolution of the cartographical data and the expected accuracy
work in a group and critically expose their work
Frontal theoretical lessons followed by lessons in the computer room to put into practice the concepts learned during the theoretical lessons.
The class is taught in Italian but slides and references are available in English.
Working students and students with certified SLD (Specific Learning Disorders), disability or other special educational needs are advised to contact the teacher at the beginning of the course to agree on teaching and examination arrangements so to take into account individual learning patterns, while respecting the teaching objectives.

Oral exam (in Italian or in English), with the presentation and the discussion on an application realized by the students in small groups (2-4 components) and verification of the knowledge of the theoretical concepts of the class.
The exam consists in an oral test in which students present (via slides) and discuss an application made in small groups (2-4 components). The application is typically inspired to the guided exercises carried out during the lectures, with appropriate insights, but can be agreed with the teacher on the basis of specific interests of students, for example a GIS analysis to be carried out as part of other classes or preparatory for the thesis.
During the exam, the theoretical knowledge of the fundamental concepts for a correct management of geographic data is also ascertained (reference systems and cartographic projections, resolutions and precisions, basic processing techniques).
The final grade takes into account the quality of the presented application (originality, type of application, employed processing techniques and analysis, strategies for solving any problems encountered), the critical discussion of the obtained results and the expositive capacity, and the knowledge of theoretical concepts.
It is preferred, but it is not mandatory, that the application is carried out in small groups consisting of 2-4 students.
It is preferable, but it is not mandatory, that the entire group takes the exam in the same exam round.
It is requested that the slides of the presented application are delivered during the examination, either by sending them by email or by delivering them on a CD, DVD or USB stick.
