What Is 'GIS'?
Definition of 'GIS'?
GIS’ is an abbreviation for 'Geographic Information Systems'. Sometimes these days, regularly referred to as Location Intelligence.
Although there are many definitions of what a GIS is, the GIS Unit at the Office of the Premier has adopted the following definition:
'a computer-based tool used to store, overlay and distribute spatial data of the same
geographical area to be able to apply manipulation, queries, analyse and presentation of
the data to enhance the decision making process'
The five main aspects that make up a GIS:
- Hardware
- Software
- Data
- Personnel
- Processes
What is Spatial Information (Geographic Information)?
It is information that is location based (spatial) and can be mapped. This generally involves:
- 'WHAT' (features, facilities, objects, assets)
- 'WHERE' (addresses, coordinates)
What GIS is NOT...
- A GIS is not simply a computer system used
only for making maps.
- A GIS is an analytical tool, used to identify
and present relationships between map and attribute data.
- A GIS is not a tool that stores maps, images or
views of a geographic area.
- A GIS is a tool that stores data from which maps,
images and views can be displayed through analyses and processes.
Benefits of a GIS
- Better management of assets, utilisation and deployment of assets
- Shared access of spatial information, thus reducing duplication of data, systems, software, staff, and other related cost items
- Facilitation of interoperability between departmental systems and functions
- Ability to perform drill-down analyses using a variety of datasets
General Questions a GIS can answer
- Location - Where is an asset?
- Condition - What is the asset?
- Patterns - How are the assets distributed?
- Trends - What has changed since...?
- Modelling - What if...?
