The Geographic Information Systems course aims to provide students with methodologies and tools useful for collection, storage, management, analysis and representation of spatially geo-referenced data. The course will address, by different degrees of detail, the main issues related to the GIS, starting from the analysis of the main data models up to their correct and precise representation, passing through the concepts of topology, database, data analysis, etc.
Expected learning outcomes
Students will gain skills and competences in georeferenced environmental data storage, query, management, analysis and visualization GIS-based concepts and techniques.
Lesson period: Second semester
(In case of multiple editions, please check the period, as it may vary)
1. Introduction Concepts and terminology; differences between GIS and CAD systems; fields of application and purposes (decision making and environmental management). 2. Cartographic concepts Map scale, projection and coordinate systems; difference between traditional cartographic approaches and digital ones. 3. Data structure geometric component (raster and vector); descriptive component (tables); topological component (relations among objects); time component. 4. Digital data entry Maps scanning and digital conversion; georeferencing; manual and/or automatic digitizing; topology definition (arc-node relations; arc direction, inclusion, adjacency); database design and implementation; cartographic symbols; final controls (constrain controls and test plots). 5. Database General concepts (records, fields, key-fields); normalization theory; Join and Relate operations; query (mathematical, conditional and logical operators).
Prerequisites for admission
No prerequisites are required. "Mathematical institutions" is strongly recommended as preparatory course
