Learning objectives
The Cartography module has the objective to provide the students with the theoretical basis of Cartography. Moreover, they will learn how to read topographic maps, to determine the coordinates of a point, to create topographical transects, and to delimit catchment areas. In the GIS module the students will learn to manage the digital geographic data, using the open source software QGIS, handling complex problems such as georepherencing of maps, management of raster and vector data formats, the extraction of information by means of geographic information systems.
Prerequisites
none
Course unit content
The Cartography and GIS modules are carried out through lectures on the theory of Cartography, on the characteristics of topographic maps and practical activities related to: determination of coordinates in geographic and kilometric reference systems; construction of topographic profiles; delimitation of river basins.
The part concerning the use of a GIS is carried out through lectures and through practical activities at the computer. Acquired knowledge of the most commonly used commands for the visualization and analysis of cartographic works, the digitalization of cartographic data with the QGIS open source software.

Teaching methods
The course is carried out through lectures and practical activities on maps and computer, 6 credits, for a total of 48 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
Practical exams.
IMPORTANT: You can access the Cartography exam only if you have passed the oral exam of Physical Geography (first semester).
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) [5/30], 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 [10/30] 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
