The goal of the course is to supply the fundamentals about the geomatics technologies related to positioning and navigation (Global Navigation Satellite Systems – GNSS, mainly GPS), to assisted guide of vehicles (Mobile Mapping Systems – MMS) and to archiving and management of geospatial data (Geographical Information Systems – GIS e WebGIS).

Syllabus outline

  • Global Navigation Satellite Systems – GNSS: introduction to GNSS; GPS: positioning and technicalities fundamentals; reference systems and frames; pseudorange and carrier phase observations modelling and processing; different kinds of GPS surveys, Network Real Time Kinematic surveys; application to vehicles positioning and navigation
  • Mobile Mapping Systems – MMS: components of a MMS and sensors; principles of sensors integration; accuracy and applications of MMS
  • Geographical Information Systems (GIS): principles and goals; GIS functionalities (raw data acquisition, data preprocessing and organization, data analysis and investigation, results interpretation); objects representation (raster and vector data structures, geometrical and topological primitives); GIS design: external, conceptual, logical and internal models; general information about WebGIS; commercial (ArcGIS) and Open Source (QGIS) GIS software

- The presentation of the mentioned items will be completed with practical exercises.
- Fundamental concepts of Positioning and Mapping are required, anyway they are shortly summarized at the beginning of the course.
- Exam procedure: oral exam, with discussion of the practical exercises developed during the course.
