Your task for this topic is to become familiar with GIS as a field of study that underpins a growing geospatial industry. In your studies you should observe that there are differences of opinion about what GIS is - and is not. Most importantly, you should recognise five common components that recur in GI applications, understand the relationships between them and their relationships to GI Science, GI Systems and GI Services.

On completion of this topic you should be able to:
  • exemplify current GIS applications,
  • recognise the presence of five components in the use of GIS,
  • explain the ideas behind these components,
  • critically assess developments in these components that have led to modern GIS,
  • explain the relationships between GI systems, science and services.
