Learning objectives
The course provides knowledge of geographic information systems as an essential tool for the management of environmental data and their representation. GIS is a powerful tool for managing, analysing, manipulating and visualizing spatial data and therefore fundamental in the planning and development decision-making process. In a continental and coastal marine environment, given the complexity and variety of spatial data available, GIS is essential to guarantee the correct use of the territory. In particular, the course develops skills for the use of open-source GIS software widespread in the professional and public administration fields. The final objective of the course is to allow the student to acquire the knowledge and skills to search, create and manipulate the most varied spatial data, in order to obtain a cartographic product of interest.
Prerequisites
Students must have successfully passed the exam of Analysis of environmental data and geostatistics (1st year).
Course unit content
In addition to theoretical knowledge, the course provides the tools for practical applications through guided exercises with real data from projects focused on territory management. QGIS and SAGA GIS software will be used to create and manipulate spatial data.
The course is divided into three modules defined on the basis of the main objectives.
i) The first part deals with the types of data that can be used in a GIS (vectors, GPS, CSV, rater, etc.) and their management within a geodatabase.
ii) Subsequently, the course explores the functions of geoprocessing and terrain analysis useful for manipulating the data created/downloaded to obtain derivatives of interest. The activities start from the management of vector and raster data to arrive at data analysis.
iii) Finally, the course focuses on static cartographic outputs and dynamic maps for the representation of environmental data and the results of the processing carried out on territorial data.
