NUMERICAL CARTOGRAPHY AND GIS
The course is aimed to provide students with principles, methods and tools at the base of Numerical Cartography and Geographic Information System (GIS). Knowledge and understanding: The student must demonstrate knowledge and understanding of the principles, methods and tools of Numerical Cartography and the GIS needed to solve theoretical and practical problems in navigation, relief and representation.
Ability to apply knowledge and understanding: The student must demonstrate how to use the theoretical and practical concepts of Numerical Cartography and the GIS to support navigation, relief and representation.
Judging autonomy: Students must be able to independently evaluate situations that are different from the standard ones presented by the teacher during the course and to adopt the best methodologies.
Communicative Skills: The student must have the ability to develop and present topics related to Numerical Cartography and GIS using the technical-scientific language correctly.
Learning Skills: The student must be able to update continuously through the consultation of texts and publications in order to acquire the ability to deepen the topics in the field of Numerical Cartography and GIS.
It is useful to have already assimilated the knowledge provided by the courses of: Mathematical Analysis 1, Physics 1, Geodesy and Navigation.
Fundamentals of Cartography (8 hours) - The representation of earth on plan: three-dimensional modeling (sphere, ellipsoid, geoid) and classification of maps; scale ratio and symbolism; geographic, Cartesian and plane coordinates; main reference systems in Italian Official Cartography: the production of the IGM (Military Geographic Institute).
Numerical Cartography formats (4 hours) - Raster format: file structure and typology, geometric and radiometric resolution; vector format: geometric primitives, topological attributes and relationships; levels of information (layers).
Digitalization of cartography (6 hours) - Acquisition of raster format: types of scanners and resolution; acquisition of the vector format: use of digitizing tablets and vectorization of digital images; raster-vector and vector-raster transformations.
Geo-reference of raster and vector files (6 hours) - Georeferencing raster images and vector graphics through conforming and affine transformations.
Automatic datum and coordinate transformations (4 hours) - Passage from geographic to plane coordinates (and vice versa); data change between WGS84, ED50 and Roma40.
GIS: Building Characteristics and Data Organization (4 hours) - GIS hardware and software components; organization of cartographic data; databases and management systems (relational and object models).
GIS functions (6 hours) - Query of GIS databases through SQL language; layer composition; layout organization; construction of thematic maps; realization of respect areas (buffer).
Digital terrain models and their construction via GIS (6 hours) - Digital Terrain Model (DTM) and methods of construction; TIN (Triangulated Irregular Network); DEM (Digital Elevation Model); continuity of the representation and use of break lines; data interpolation methods starting from level curves and quoted points.
Numerical cartography and GIS for navigation (4 hours) - Digital nautical charts; electronic cards; ECS (Electronic Chart System; ECDIS (Electronic Chart Display and Information System).
The course includes the following topics.
Fundamentals of Cartography (8 hours).
Numerical Cartography formats (4 hours).

The objective of the examination is to check the level of achievement of the training goals previously indicated.
The student is called to describe theoretical and practical aspects of the course. During the oral examination, the ability to expose the subjects studied, and to link and compare different aspects considered during the course is evaluated.
Lectures are in Italian. The professor is fluent in English and is available to interact with students in English, also during the examination.
