Expected learning outcomes
Module 1: Territorial Information System
The course aims at providing an advanced understanding of GIS by showing their utility in practical environmental and territorial applications; it also aims at providing students with the necessary ability to solve spatial problems.
At the end of the course, students must demonstrate to have acquired the following competences:
- understand characteristics of spatial data, including Digital Elevation Models and orthophotos;
- to understand and discriminate between the different reference systems in which these data are expressed
- to be able to associate raster and vector data to the appropriate reference system and/or cartographic representation;
- to be able to import, export and convert data in raster and vector format between different reference systems and cartographic projections;
- to understand the characteristics of vector and raster structures and the information necessary to georeference them
- to understand spatial interpolation techniques for the production of raster data (DEM and orthophotos); -
- to be able to carry out queries and spatial selection on vector data and attributes;
- to be able to use the raster calculator to select and analyse raster data
- to understand and successfully apply georeferencing techniques on raster data;
- to be able to break down problems into the steps required to solve it, identifying the most appropriate GIS tools for each case.
Module 2: statistics
Describe the phenomena by the main statistical indicators; Plan a sample surveys; Use the methodology of the analysis of variance at 1 factor; understand the results of statistical surveys.

Assessment methods and Criteria
STATISTICS.
Test with open and closed questions and excercises with the use of pc.
TERRITORIAL INFORMATION SYSTEMS:
Learning will be assessed through an oral examination with questions on the theoretical part of the course, followed by a project, which will demonstrate that the student has acquired the required skills in the elaboration, visualization and query of data in QGIS.
To successfully complete the course, the student must demonstrate, both in the oral examination and in the practical part, to have acquired the skills listed as the learning outcomes.
In the final assessment, the oral examination accounts for 60% of the vote and aims to verify the acquisition of theoretical and methodological knowledge. The project accounts for the remaining 40%, and aims to verify the ability of the student to apply the theoretical knowledge and his/her self-learning abilities. Students with LSD should contact the teacher to plan compensatory and dispensatory measures, following the guidelines provided by the University.
