A map is a database, a tool for spatial analysis and decision support
and a method of communicating information. Geographical Information Systems,
GIS, have developed over the last 40 years or so and now make a substantial
contribution to the information society and knowledge economy. Annual
growth rates in the GI industry exceed 10% due to demand for more integrated
and better targeted resource management, more complete understanding of
spatially distributed systems and a roll-out of location based services.
In this topic you will learn something about modern applications of GI
and the components that contribute to an application. In no particular
order, the components are:
- organisational and societal context
- a body of knowledge and ideas
They provide a framework for your studies in geospatial information.
