Question 6: What are the advantages of GIS?
In theory, all GIS processes
can be undertaken manually. Before GIS, analysis procedures would have
been manually undertaken using transparent
run through very slow and cumbersome machines with far less power than the
machines of today. The essential advantage of modern GIS, however, is that
all the functionality for working with multiple sets of geographic information
are grouped and automated within one piece of software. In addition it benefits
from modern computer efficiency and speed.
