GIS is a methodology of presenting various types of information
pertaining to particular place in a simple way. The method
uses a system of layering very similar to the methods that
are used by graphics packages such as Photoshop or desktop
Using layers with geographic information involves each "layer"
containing data about a specific characteristic - vegetation
type; main roads; water bodies etc.
By combining the power of computer graphics and databases,
GIS allows digital maps to be 'intelligent'. This means that
GIS can be used to answer such questions as:
'where are my customers?'
'what is the area of this housing estate and how many
people live there?
what is the average income of my target age group within
a 20 minute drive of this shop?
if we close this hospital, how far will people have to
drive to get to the next nearest open hospital?
or, more importantly,
'where is the nearest pub?'
