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
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.
