Question 5: What are the modern systems used for combining geographic information?
Traditionally, the most common method to combine geographic
information is cartographically within a paper map or some sort of
map overlay.
Now, the input,
storage and display of geographical information are realized in a computer.
Once in the computer, the features and themes can be manipulated, combined
and analyzed to generate new information. The software designed to do this
is called GIS software.
As well as the software, the following elements are required to be able
to run GIS:
-
Modern PC
-
Software and data input devices, ideally a CD-drive
-
Output devices, including a monitor and a printer
-
Human operator
