GIS and Spatial Data Management
Module Leader
Professor Stephen Hallett
Aim
Geographical information is increasingly prevalent in our daily life, affecting personal leisure activities as much as business services and the workplace. Geographical information represents a key theme in environmental management and it has been estimated that some 80% of the data used for environmental, business and policy-oriented decision-making is geographical in nature. Such spatial data requires a structured approach in its management if the maximum benefit is to be derived from analysis and dissemination. This module provides a solid introduction to the issues concerning the management of spatial information and the tools to do so, with a predominant focus on ESRI’s software solutions.
Syllabus
Spatial data models and database structures – vectors, rasters, topology, ordered and indexed lists, hierarchical, network, relational, object oriented, hybrid, metadata.
Mapping fundamentals – geodesy, projections, cartography, abstraction of the real world into map form.
Analysis approaches – database manipulation, reclassification, overlay, spatial modelling.
Data specification and standards – use cases, interoperability, INSPIRE.
