||The efficient and effective management, display and analysis of spatial information are integral skills for contemporary transportation, logistics and infrastructure professionals. Meeting these requirements has been revolutionised by the development of Geographical Information Systems (GIS). This unit introduces students to the theory and practice of GIS, with a particular focus on applications in transportation, logistics and infrastructure management. The unit begins by introducing students to the \\\'building blocks\\\' of GIS systems, including data structures, relational databases, spatial queries and analysis. We then focus on sources of spatial data including GPS, remote sensing, and web-based sources highlighting both the potential and challenges associated with integrating each data source within a GIS environment. The unit then takes a hands-on focus, using the latest GIS software to analyse several problems of interest (e.g., establishing demand for a new rail/bus service, planning a routing and scheduling service for a delivery firm, or identifying aircraft noise violations around an airport). Students completing the unit will be able to conduct and evaluate a GIS case study in terms of implementation of a data model, the use of appropriate GIS tools and techniques, benefits and barriers of the implemented system, and how the system could be improved. This unit will appeal to all students interested in the spatial impact of decision-making.
