GIS in Geography

1. Using GIS in Geography

2. GIS allows us to view, understand, question, interpret,
and visualize data in many ways that reveal
relationships, patterns, and trends in the form of maps,
globes, reports, and charts.

3. GIS is a changeable
map!! It is a series of
complex geographical
data and is simply a
route by which this
data can be analysed
and explored.

4. GIS allows us to overlay different types of information
onto maps of the same area. This is just like using
tracing paper or transparent overlays. With GIS we can
link map data with information that is not shown on
maps. This linked information can be anything!
However, as the data is digital these overlays can be
created using lots of data and then manipulated to
produce original maps and help us make informed
geographical decisions.

5. GIS is everywhere! For
example: Emergency
services such as the Fire
Brigade, Police and
Ambulance service have
all used GIS to speed up
response times to
accidents and
emergencies thus saving
lives.
Even pizza companies utilise GIS
to ensure that deliveries reach
households efficiently!

6. A GIS helps you answer questions and solve problems by looking
at your data in a way that is quickly understood and easily shared

7. Advantages of GIS
The key advantage of GIS is that all the
functionality for working with multiple sets of
geographic information are embedded into
one piece of software and it is quick and
efficient. For example it can:
