Training objectives
- Nowadays cartographic representation and production are conducted in GIS (Geographic Information System) environment. The GIS is the preferred tool to manage the spatial/geographic data: from their collection, passing through the analysis and ending with the maps production.
The main aim is to offer to the student the base knowledge to understand and use principal GIS functions. Also the scientific fundaments and the theoretical background (GIScience) that support the use of this tool will be briefly presented. After an introduction on the more used methodologies, the lessons focus will be on the modules useful in the geoscience applications (Geoinformatics).
Many territorial operators use the GIS to study and manage environmental phenomena. Thus the tool, useful to research, can be spent also in professional works.
The theoretical competences will be always followed by the illustration of an applicative case study. The practical exercitations at PC aim to acquire the main GIS capabilities:
-build of a Geodatabase
-pre-processing and optimization of different data: topography, remote sensing, survey
-visualization and basic spatial analysis
-interpretation and cartographic production (geomorphological, geological, risk mapping, etc.). Prerequisites
- Basic geographical knowledge (coordinate systems, datum and map projections)
Basic computer knowledge Course programme
- The course includes 48 hours of teaching divided between theoretical lessons (24 hours) and and practical computer exercises (24 hours).
The main topics that will be covered during the theoretical lessons:
Geomatics. The science and technology of problem solving. Introduction to GIS and historical hints. GIS principal applications. The representation of geographic data, vector and raster models.(8 hours)
Brief recalls to basic of cartography: Earth shape, geoid and ellipsoid, coordinate system, Datum and projections. The Italian cartography. Maps interpretation: relief analysis, symbols in topographic and thematic maps. Errors and uncertainty in geodata, numerical cartography and online data. Topology and spatial analysis.(8 hours)
Map building and the main methodologies of data inputs: the survey and GPS, basis of remote sensing, photointerpretation and images analysis. The topography: Digital elevation models building, analysis and geomorphometry.(8 hours)
Pc exercises will be on the main theoretical topic, some example:
Spatial data implementation, the georeferenced, the building of a Geo-database.
Extraction of a topographic profile from a DTM, exporting and elaboration applied to the draw of a geological profile in GIS.
Images and DEM analysis.
Enhancing visualization and representation for the geomorphological and geological mapping. Didactic methods
- The lessons will be theoretical, case studies and practical exercises at the computer laboratory
Learning assessment procedures
- 1 PC exercise: that will be on a combination of already applied GIS procedures
1 oral exam: starting from the discussion on the exercise results, questions will be, successively, on some of the topics explained in the theoretical lessons Reference texts
- Lecture notes
