This module focuses on the practical use of GIS for dissertations. After an introductory `refresher' of GIS basics it will review the different techniques that can be used to create and edit data in a GIS, as well as existing digital databases from which map data can be extracted and downloaded. Particular attention will be given to Ordnance Survey mapping for the UK, but other international resources will also be discussed. The module will emphasise issues of error and uncertainty as they apply to spatial data and introduce the use of the ArcGIS ModelBuilder as a way of documenting and efficiently repeating more complex analysis procedures. Assessment will be through a small group project involving the download, integration, analysis and display of spatial data. Taught in the second half of the semester.
