Learning objectives
The course aims to provide basic knowledge of the physical phenomena that occur in the atmosphere to explain the different climatic conditions that characterize the earth's surface. The second part of the course, mainly carried out through exercises, provides the basic knowledge for a profitable use of the topographic map, a fundamental tool for reporting the geological data collected on the ground. Ability to trace topographic profiles and delineation of hydrographic basins. Knowledge on the use of QGIS is mainly based on various practical computer activities.
Prerequisites
None
Course unit content
The course provides knowledge on the shape of the Earth, on the motions of the planet and the effects of the inclination of the Earth's axis; on the structure and physical characteristics of the atmosphere and solar radiation; on atmospheric pressure and winds; on atmospheric humidity, types of precipitation and phenomena of cyclonic perturbations; on terrestrial climates and their classification.
It also provides the theoretical and practical elements of classical and digital cartography and the notions for the management of geographic data through the use of geographic information systems (QGIS software)

Teaching methods
The course is carried out through lectures and practical activities on maps and computer, 12 credits, for a total of 96 hours. Acquired knowledge of the most commonly used commands for the visualization and analysis of the cartographic works, the digitalization of cartographic data and the creation of layouts through QGIS. Practical applications of using a GIS are performed along the course.
The slides used to support the lessons are uploaded on a weekly basis on the Elly platform. To download the slides, you need to register for the online course. All lessons are also recorded on the Teams platform and can be viewed deferred, if necessary, within about one month from the delivery of the lesson.
The slides are considered an integral part of the teaching material, and are to be used to integrate the information received during the course with the necessary insights to be done individually on the indicated textbooks. Non-attending students are reminded to check the didactic material available and the information provided by the teacher through the Elly platform.
Assessment methods and criteria
The 3 exams relating to the Physical Geography, Cartography and GIS course must be passed in sequence:
- Physical Geography (one oral exam, 1 vote)
- Cartography (one practical exam, 1 vote)
- GIS (one practical exam, 1 vote)
The final grade for the Physical Geography, Cartography and GIS exam is given by the average of the 3 grades obtained in Physical Geography (1 grade), Cartography (1 grade) and GIS (1 grade). The final grade is recorded on the GIS exam, after passing it.
The exam of Physical Geography takes place through an oral interview. Four questions of [8/30] each will be asked (the grade of 32/30 corresponds to 30L), for a typical duration of around 30-40 minutes. If a question is completely unanswered or completely wrong, the maximum mark achievable in the exam will be [22/30].
The grade of the oral exam is communicated immediately at the end of the exam itself
Practical exams.
You can access the Cartography exam only if you have passed the oral exam of Physical Geography.
The GIS exam is accessed only if the Cartography test has been passed.
- Cartography Mod: the exam is divided into two parts (the grade of the first part is added to the grade of the second part). The Cartography Mod. is passed if an overall grade> = 18/30 is obtained and if no serious errors are made in the second part (ie no grade with 0).
1st part) Coordinates of a point in the 4 coordinate systems (UTM kilometric, Gauss-Boaga kilometric, Italian geographic and international geographic) [10/30], theory test of 5 questions with closed answers [5/30].
2nd part) construction of a topographic profile [10/30] and delimitation of a hydrographic basin [5/30] from a topographic map.
The grade of the practical exam is possibly communicated within 24 hours
- Mod. GIS: Execution of an exercise to verify the knowledge acquired in data management and use of some fundamental functions of QGIS. The problem to be solved is based on the exercises seen during the course and is divided into 3 parts of [10/30] each.
The grade of the practical exam is possibly communicated within 1-3 days
